In modern times industries have become a very important part of an economy. They provide employment to a large labour force and contribute significantly in the total national wealth/income.
9.1. Types of Industries
- On the basis of size, capital investment and labour force employed, industries are classified as large, medium, small scale, and cottage industries.
- On the basis of ownership, industries are categorized as:
- public sector,
- private sector, and
- joint and cooperative sector,
- Public sector enterprises are government/state controlled companies or corporations funded by governments. Industries of strategic and national importance are usually in the public sector.
- Industries are also classified on the basis of the use of their products such as:
- basic goods industries,
- capital goods industries
- intermediate goods industries, and
- consumer goods industries.
- Another method of classifying industries is on the basis of raw materials used by them. Accordingly, these can be:
- agriculture based industries,
- forest-based industries,
- mineral-based industries, and
- industrially processed raw material based industries.
- Another common classification of industries is based on the nature of the manufactured products. Eight classes of industries, thus identified are:
- Metallurgical Industries,
- Mechanical Engineering Industries,
- Chemical and Allied Industries,
- Textile Industries,
- Food Processing Industries,
- Electricity Generation,
- Electronics and
- Communication Industries.
9.2. Location of Industries
- Location of industries is influenced by several factors like access to raw materials, power, market, capital, transport and labour, etc. Relative significance of these factors varies with time and place. There is a strong relationship between raw material and type of industry. It is economical to locate the manufacturing industries at a place where cost of production and delivery cost of manufactured goods to consumers are the least. Transport costs, to a great extent, depend on the nature of raw materials and manufactured products.
A brief description of factors influencing the location of industries are given below:
- Raw Materials: Industries using weight-losing raw materials are located in the regions where raw materials are located. Similarly, the locations of the pulp industry, copper smelting and pig iron industries are located near their raw materials. In iron and steel industries, iron ore and coal both are weight-losing raw materials. Therefore, an optimum location for iron and steel industries should be near raw material sources. This is why most of the iron and steel industries are located either near coalfields (Bokaro, Durgapur, etc.) or near sources of iron ore (Bhadravati, Bhilai, and Rourkela). Similarly, industries based on perishable raw materials are also located close to raw material sources.
- Power: Power provides the motive force for machines, and therefore, its supply has to be ensured before the location of any industry. However, certain industries, like aluminium and synthetic nitrogen manufacturing industries tend to be located near sources of power because they are power intensive and require huge quantities of electricity.
- Market: Markets provide the outlets for manufactured products. Heavy machine, machine tools, heavy chemicals are located near the high demand areas as these are market orientated. Cotton textile industry uses a non-weight-losing raw material and is generally located in large urban centres, e.g. Mumbai, Ahmedabad, Surat, etc. Petroleum refineries are also located near the markets as the transport of crude oil is easier and several products derived from them are used as raw material in other industries. Koyali, Mathura and Barauni refineries are typical examples. Ports also play a crucial role in the location of oil refineries.
- Transport: Have you ever tried to find out the reasons for the concentration of industries in Mumbai, Chennai, Delhi and in and around Kolkata? It was due to the fact that they initially became the nodal point having transport links. The industries shifted to interior locations, only when railway lines were laid. All major industrial plants are located on the trunk rail routes.
- Labour: Industries require skilled labour. In India, labour is quite mobile and is available in large numbers due to our large population.
- Historical Factors: During the initial phase of colonization, manufacturing activities received new impetus provided by the European traders. Places like Murshidabad, Dhaka, Bhadohi, Surat, Vadodara, Kozhikode, Coimbatore, Mysore, etc. emerged as important manufacturing centres. In the subsequent industrial phase of colonialism, these manufacturing centres experienced rapid growths due to competition from the goods manufactured in Britain and the discriminatory policies of colonial power. In the last phase of colonialism, the British promoted few industries in selected areas. This led to larger spatial coverage by different types of industries in the country.
- Industrial Policy: India, being a democratic country aims at bringing about economic growth with balanced regional development. Establishment of iron and steel industry in Bhilai and Rourkela were based on the decision to develop backward tribal areas of the country. At present, the government of India provides lots of incentives to industries located in backward areas.
9.3. Major Industries
- The iron and steel industry are basic to the industrial development of any country. The cotton textile Industry is one of our traditional industries. The sugar Industry is based on local raw materials which prospered even in the British period.
9.3.1. The Iron and Steel Industry
- The development of the iron and steel industry opened the doors to rapid industrial development in India. Almost all sectors of the Indian industry depend heavily on the iron and steel industry for their basic infrastructure.
- The other raw materials besides iron ore and coking coal, essential for the iron and steel industry are limestone, dolomite, manganese and fire clay. All these raw materials are gross (weight losing), therefore, the best location for the iron and steel plants is near the source of raw materials.
- In India, there is a crescent shaped region comprising parts of Chhattisgarh, Northern Orissa, Jharkhand and western West Bengal, which is extremely rich in high grade iron ore, good quality coking coal and other supplementing raw materials.
- The Indian iron and steel industry consist of large integrated steel plants as well as mini steel mills. It also includes secondary producers, rolling mills and ancillary industries.
Integrated Steel Plants
- TISCO: The Tata Iron and Steel plant lies very close to the Mumbai-Kolkata railway line and about 240 km away from Kolkata, which is the nearest port for the export of steel. The rivers Subarnarekha and Kharkai provide water to the plant. The iron ore for the plant is obtained from Noamundi and Badam Pahar and coal is brought from Joda mines in Orissa. Coking coal comes from Jharia and west Bokaro coalfields.
- IISCO: The Indian Iron and Steel Company (IISCO) set up its first factory at Hirapur and later on another at Kulti. In 1937, the Steel corporation of Bengal was constituted in association with IISCO and set up another iron and steel producing unit at Burnpur (West Bengal). All the three plants under IISCO are located very close to Damodar valley coalfields (Raniganj, Jharia, and Ramgarh). Iron ore comes from Singhbhum in Jharkhand. Water is obtained from the Barakar River, a tributary of the Damodar. All the plants are located along the Kolkata-Asansol railway line. Unfortunately, steel production from IISCO fell considerably in 1972-73 and the plants were taken over by the government.
- Visvesvaraya Iron and Steel Works Ltd. (VISL): The third integrated steel plant, the Visvesvaraya Iron and Steel Works, initially called the Mysore Iron and Steel Works, is located close to an iron ore producing area of Kemmangundi in the Baba Budan hills. Limestone and manganese are also locally available. But this region has no coal. At the beginning, charcoal obtained by burning wood from nearby forests was used as fuel till 1951. Afterwards, electric furnaces were installed which use hydroelectricity from the Jog Falls hydel power project. The Bhadravati river supplies water to the plant. This plant produces specialized steels and alloys.
After independence, during the Second Five Year Plan (1956-61), three new integrated steel plants were set up with foreign collaboration: Rourkela in Odisha, Bhilai in Chhattisgarh and Durgapur in West Bengal. These were public sector plants under Hindustan Steel Limited (HSL). In 1973, the Steel Authority of India Limited (SAIL) was created to manage these plants.
- Rourkela Steel Plant: The Rourkela Steel plant was set up in 1959 in the Sundargarh district of Orissa in collaboration with Germany. The plant was located on the basis of proximity to raw materials, thus, minimizing the cost of transporting weight losing raw material. This plant has a unique locational advantage, as it receives coal from Jharia (Jharkhand) and iron ore from Sundargarh and Kendujhar. The Hirakud project supplies power for the electric furnaces and water is obtained from the Koel and Sankh rivers.
- Bhilai Steel Plant: The Bhilai Steel Plant was established with Russian collaboration in Durg District of Chhattisgarh and started production in 1959. The iron ore comes from Dalli-Rajhara mine (Fig. 8.6), coal comes from Korba and Kargali coal fields. The water comes from the Tanduladam and the power from the Korba Themal Power Station. This plant also lies on the Kolkata-Mumbai railway route. The bulk of the steel produced goes to the Hindustan Shipyard at Visakhapatnam.
- Durgapur Steel Plant: Durgapur Steel Plant, in West Bengal, was set up in collaboration with the government of the United Kingdom and started production in 1962. This plant lies in Raniganj and Jharia coal belt and gets iron ore from Noamundi (Fig. 8.7). Durgapur lies on the main Kolkata-Delhi railway route. Hydel power and water are obtained from the Damodar Valley Corporation (DVC).
- Bokaro Steel Plant: This steel plant was set up in 1964 at Bokaro with Russian collaboration. This plant was set up on the principle of transportation cost minimization by creating Bokaro-Rourkela combine. It receives iron ore from the Rourkela region and the wagons in return take coal to Rourkela. Other raw materials come to Bokaro from within a radius of about 350 km. Water and Hydel power is supplied by the Damodar Valley Corporation.
- Other Steel Plants: New steel plants which were set up in the Fourth Plan period are away from the main raw material sources. All the three plants are located in South India. The Vizag Steel Plant, in Visakhapatnam in Andhra Pradesh is the first port based plant which started operating in 1992. Its port location is of advantage. The Vijayanagar Steel Plant at Hospet in Karnataka was developed using indigenous technology. This uses local iron ore and limestone. The Salem Steel Plant in Tamil Nadu was commissioned in 1982.
Apart from these major steel plants, there are more than 206 units located in different parts of the country. Most of these use scrap iron as their main raw material, and process it in electric furnaces.
9.3.2. The Cotton Textile Industry
- The cotton textile industry is one of the traditional industries of India. In the ancient and the medieval times, it used to be only a cottage industry. India was famous worldwide for the production of muslin, a very fine variety of cotton cloth, calicos, chintz and other different varieties of fine cotton cloth. The development of this industry in India was due to several factors. One, it is a tropical country and cotton is the most comfortable fabric for a hot and humid climate.
- Second, a large quantity of cotton was grown in India. Abundant skilled labour required for this industry was available in this country. In fact, in some areas the people were producing cotton textiles for generations and transferred the skill from one generation to the other and in the process perfected their skills.
- Initially, the British did not encourage the development of the indigenous cotton textile industry. They exported raw cotton to their mills in Manchester and Liverpool and brought back the finished products to be sold in India. This cloth was cheaper because it was produced at mass scale in factories in U.K. as compared to the cottage based industries of India. In 1854, the first modern cotton mill was established in Mumbai. This city had several advantages as a cotton textile manufacturing centre. It was very close to the cotton producing areas of Gujarat and Maharashtra. Raw cotton used to be brought to Mumbai port to be transported to England. Therefore, cotton was available in Mumbai city itself. Moreover, Mumbai even then was the financial centre and the capital needed to start an industry was available there. As a large town, providing employment opportunities attracted labour in large numbers. Hence, cheap and abundant labour too was available locally. The machinery required for a cotton textile mill could be directly imported from England. Subsequently, two more mills, the Shahpur Mill and the Calico Mill were established in Ahmedabad. By 1947, the number of mills in India went up to 423 but the scenario changed after partition, and this industry suffered a major recession. This was due to the fact that the most of the good quality cotton growing areas had gone to West Pakistan and India was left with 409 mills and only 29 per cent of the cotton producing area.
- After Independence, this industry gradually recovered and eventually flourished. In 1998, India had 1782 mills; of which, 192 mills were in the public sector and 151 mills in the cooperative sector. The largest number, that is, 1,439 mills were in the private sector. The cotton textile industry in India can be broadly divided into two sectors, the organized sector and the decentralized sector. The decentralized sector includes cloth produced in handlooms (including Khadi) and power looms. The production of the organized sector has drastically fallen from 81 per cent in the mid-twentieth century to only about 6 per cent in 2000. At present, the power looms on the decentralized sector produce more than 59 percent and the handloom sector produces about 19 per cent of all cotton cloth produced in the country.
- Cotton is a “pure” raw material which does not lose weight in the manufacturing process. so other factors, like, power to drive the looms, labour, capital or market may determine the location of the industry. At present the trend is to locate the industry at or close to markets, as it is the market that decides what kind of cloth is to be produced. Also, the market for the finished products is extremely variable, therefore, it becomes important to locate the mills close to the market. After the first mills were set up in Mumbai and Ahmedabad in the second half of the nineteenth century, the cotton textile industry expanded very rapidly. The number of units increased dramatically. The Swadeshi movement gave a major impetus to the industry as there was a call for boycotting all British made goods in favour of Indian goods.
- After 1921, with the development of the railway network other cotton textile centres expanded rapidly. In southern India, mills were set up at Coimbatore, Madurai and Bangalore. In central India, Nagpur, Indore, Solapur and Vadodara became cotton textile centres. Cotton textile mills were set up at Kanpur based on local investment. Mills were also set up at Kolkata due to its port facilities.
- The development of hydro-electricity also favoured the location of the cotton textile mills away from the cotton producing areas. The rapid development of this industry in Tamil Nadu is the result of the abundant availability of hydel power for the mills. Lower labour costs at centres like Ujjain, Bharuch, Agra, Hathras, Coimbatore and Tirunelveli also caused industries to be located away from cotton producing areas.
- Thus, the cotton textile industry is located in almost every state in India, where one or more of the locational factors have been favorable. The importance of raw materials has given way to market or to a cheaper local labour force or it may be the availability of power. Presently, the major centres of the cotton textile industry are Ahmedabad, Bhiwandi, Solapur, Kolhapur, Nagpur, Indore and Ujjain. All these centres are the traditional centres and are located close to the cotton producing regions. Maharashtra, Gujarat and Tamil Nadu are the leading cotton producing states. West Bengal, Uttar Pradesh, Karnataka, and Punjab are the other important cotton textile producers.
- Tamil Nadu has the largest number of mills and most of them produce yarn rather than cloth. Coimbatore has emerged as the most important centre with nearly half the mills located there. Chennai, Madurai, Tirunelveli, Tuticorin, Thanjavur, Ramanathapuram and Salem are the other important centres.
- In Karnataka, the cotton textile industry has developed in the cotton producing areas in the north-eastern part of the state. Davangere, Hubli, Bellary, Mysore and Bangalore are important centres. In Andhra Pradesh, the cotton textile industry is located in the cotton producing Telangana region, where most of the mills are spinning mills producing yarn. The important centres are Hyderabad, Secunderabad, Warangal and Guntur.
- In Uttar Pradesh, Kanpur is the largest centre. Some of the other important centres are Modinagar, Hathras, Saharanpur, Agra and Lucknow. In West Bengal, the cotton mills are located in the Hugli region. Howrah, Serampore, Kolkata and Shyamnagar are the important centres.
9.3.3. Sugar Industry
- The sugar industry is the second most important agro-based industry in the country.
- India is the largest producer of both sugarcane and cane sugar and contributes about 8 percent of the total sugar production in the world. Besides, khandsari and gur or jaggery are also prepared from sugarcane.
- This industry provides employment for more than 4 lakh persons directly and a large number of farmers indirectly.
- Sugar industry is a seasonal industry because of the seasonality of raw materials.
- Development of the industry on modern lines dates back to 1903, when a sugar mill was started in Bihar. Subsequently, sugar mills were started in other parts of Bihar and Uttar Pradesh. In 1950-51, 139 factories were in operation producing 11.34 lakh tonnes of sugar. The number of sugar factories rose to 506 and production to 176,99 lakh tones in 2000-01.
Location of the Sugar Industry
- Sugarcane is a weight-losing crop. The ratio of sugar to sugarcane varies between 9 to 12 per cent depending on its variety. Its sucrose content begins to dry during haulage after it has been harvested from the field. Better recovery of sugar is dependent upon its being crushed within 24 hours of its harvesting. Sugar factories hence, are located within the cane producing regions.
- Maharashtra has emerged as a leading sugar producer in the country and produces more than one-third of the total production of the sugar in the country. There are 119 sugar mills in the state in a narrow belt extending from Manmad in the north to Kolhapur in the south. There are 87 mills in the cooperative sector.
- Uttar Pradesh is the second largest producer of sugar. The sugar factories are concentrated in two belts – the Ganga-Yamuna doab and the tarai region. The major sugar producing centres in the Ganga -Yamuna doab is Saharanpur, Muzaffarnagar, Meerut, Ghaziabad, Baghpat and Bulandshahr districts; while Kheri Lakhimpur, Basti, Gonda, Gorakhpur, Bahraich are important sugar producing districts in the Tarai region. In Tamil Nadu, sugar factories are located in Coimbatore, Vellore, Tiruvannamalai, Villupuram and Tiruchchirappalli districts. Belgaum, Bellary, Mandya, Shimoga, Bijapur, and Chitradurg districts are the major producers in Karnataka. The industry is distributed in the coastal regions i.e. East Godavari, West Godavari, Visakhapatnam districts and Nizamabad, and Medak districts of Telangana alongwith Chittoor district of Rayalaseema.
- The other States which produce sugar are Bihar, Punjab, Haryana, Madhya Pradesh and Gujarat. Saran, Champaran, Muzaffarnagar, Siwan, Darbhanga, and Gaya are the important sugarcane producing districts in Bihar.
- The relative significance of Punjab has declined, although Gurdaspur, Jalandhar, Sangarur, Patiala and Amritsar are major sugar producers.
- In Haryana, sugar factories are located in Yamuna Nagar, Rohtak, Hissar and Faridabad districts.
- Sugar industry is comparatively new in Gujarat. Sugar mills are located in the cane growing tracts of Surat, Junagarh, Rajkot, Amreli, Valsad and Bhavnagar districts.
9.3.4. Petrochemical Industries
- This group of industries has been growing very fast in India. A variety of products come under this category of industries. In the 1960s, demand for organic chemicals increased so fast that it became difficult to meet this demand. At that time, the petroleum refining industry expanded rapidly.
- Many items are derived from crude petroleum, which provide raw materials for many new industries, these are collectively known as petrochemical industries. This group of industries is divided into four sub-groups:
- synthetic fibre,
- elastomers, and
- surfactant intermediate.
- Mumbai is the hub of the petrochemical industries. Cracker units are also located in Auraiya (Uttar Pradesh), Jamnagar, Gandhinagar and Hajira (Gujarat), Nagothane, Ratnagiri (Maharashtra), Haldia (West Bengal) and Visakhapatnam (Andhra Pradesh).
- Three organisations are working in the petrochemical sector under the administrative control of the Department of Chemicals and Petrochemicals.
- First is the Indian Petrochemical Corporation Limited (IPCL), a public sector undertaking. It is responsible for the manufacture and distribution of the various petrochemicals like polymers, chemicals, fibres and fibre intermediates.
- Second is the Petrofils Cooperative Limited (PCL), a joint venture of the Government of India and Weaver’s Cooperative Societies. It produces polyester filament yarn and nylon chips at its two plants located at Vadodara and Naldhari in Gujarat.
- Third is the Central Institute of Plastic Engineering and Technology (CIPET), involved in imparting training in the petro-chemical industry.
- Polymers are made from ethylene and propylene. These materials are obtained in the process of refining crude oil. Polymers are used as raw materials in the plastic industry. Among polymers, polyethylene is a widely used thermoplastic.
- Plastic is first converted into sheets, powder, resin and pellets, and then used in manufacturing plastic products. Plastic products are preferred because of their strength, flexibility, water and chemical resistance and low prices. Production of plastic polymers started in India in the late fifties and the early sixties using other organic chemicals. T
- The National Organic Chemicals Industries Limited (NOCIL), established in the private sector in 1961, started the first naphtha based chemical industry in Mumbai. Later, several other companies were formed. The plants located at Mumbai, Barauni, Mettur, Pimpri and Rishra are the major producers of plastic materials. About 75 percent of these units are in the small scale sector.
- The industry also uses recycled plastics, which constitutes about 30 per cent of the total production. Synthetic fibres are widely used in the manufacturing of fabrics because of their inherent strength, durability, washability, and resistance to shrinkage. Industries manufacturing nylon and polyester yarns are located at Kota, Pimpri, Mumbai, Modinagar, Pune, Ujjain, Nagpur and Udhna. Acrylic staple fibre is manufactured at Kota and Vadodara.
- Though plastics have become inseparable items in our daily use and they have affected our lifestyle. But due to its non-biodegradable quality it has emerged as the greatest threat to our environment. Hence, use of plastic is being discouraged in different states of India.
9.3.5. Knowledge based Industries
- The advancement in information technology has had a profound influence on the country’s economy. The Information Technology (IT) revolution opened up new possibilities of economic and social transformation. The IT and IT enabled business process outsourcing (ITESBPO) services continue to be on a robust growth path.
- Indian software industry has emerged as one of the fastest growing sectors in the economy. Exports of the Indian software and services sector were Rs. 78,230 crores in 2004-05 which is approximately 30-32 per cent increase from the previous year.
- The software industry has surpassed electronic hardware production. The Indian government has created a number of software parks in the country.
- The IT software and services industry account for almost 2 percent of India’s GDP. India’s software industry has achieved a remarkable distinction for providing quality products.
- A large number of Indian software companies have acquired international quality certification. A majority of the multinational companies operating in the area of information technology have either software development centres or research development centres in India.
- However, in the hardware development sector, India is yet to make any remarkable achievements. A major impact of this growth has been on employment creation, which is almost doubled every year.
9.4. Liberalization, Privatization, Globalization (LPG) and Industrial Development in India
- The new Industrial Policy was announced in 1991. The major objectives of this policy were to build on the gains already made, correct the distortions or weaknesses that have crept in, maintain a sustained growth in productivity and gainful employment and attain international competitiveness.
- Within this policy, measures initiated are:
- abolition of industrial licensing,
- free entry to foreign technology,
- foreign investment policy,
- access to capital market,
- open trade,
- abolition of phased manufacturing programme, and
- liberalized industrial location programme.
- The policy has three main dimensions: liberalization, privatization and globalization.
- The industrial licensing system has been abolished for all except six industries related to security, strategic or environmental concerns. At the same time, the number of industries reserved for the public sector since 1956 have been reduced from 17 to 4. Industries related to atomic energy; substances specified in the Schedule of the Department of Atomic Energy as well as Railways have remained under the public sector.
- The government also has decided to offer a part of the shareholdings in the public enterprises to financial institutions, general public and workers. The threshold limits of assets have been scrapped and no industry requires prior approval for investing in the delicensed sector. They only need to submit a memorandum in the prescribed format.
- In the new industrial policy, Foreign Direct Investment (FDI) has been seen as a supplement to the domestic investment for achieving a higher level of economic development. FDI benefits the domestic industry as well as the consumers by providing technological upgradation, access to global managerial skills and practices, optimum use of natural and human resources, etc. Keeping all this in mind, foreign investment has been liberalized and the government has permitted access to an automatic route for Foreign Direct Investment.
- The government has also announced changes in the industrial location policies. Industries are discouraged in or very close to large cities due to environmental reasons.
- The industrial policy has been liberalized to attract private investors both domestic and multinationals. New sectors like, mining, telecommunications, highway construction and management have been thrown open to private companies. In spite of all these concessions, Foreign Direct Investment has not been up to the expectation. There has been a big gap between approved and actual foreign direct investment, even though the numbers of foreign collaborations are increasing. Larger parts of this investment have gone to domestic appliances, finance, services, electronics and electrical equipment, and food and dairy products.
- Globalization means integrating the economy of the country with the world economy. Under this process, goods and services along with capital, labour and resources can move freely from one nation to another. The thrust of globalization has been to increase domestic and external competition through extensive application of market mechanisms and facilitating dynamic relationships with the foreign investors and suppliers of technology. In Indian context, this implies:
- opening of the economy to foreign direct investment by providing facilities to foreign companies to invest in different fields of economies activity in India;
- removing restrictions and obstacles to the entry of multinational companies in India;
- allowing Indian companies to enter into foreign collaboration in India and also encouraging them to set up joint ventures abroad;
- carrying out massive import liberalization programmes by switching over from quantitative restrictions to tariffs in the first place, and then bringing down the level of import duties considerably; and
- instead of a set of export incentives, opting for exchange rate adjustments for promoting export.
- A breakup of foreign collaboration approval reveals that the major share went to core, priority sectors while the infrastructural sector was untouched.
- Further, the gap between developed and developing states has become wider. Major share of both domestic investment as well as foreign direct investment went to already developed states. For example, out of the total proposed investment by the industrial entrepreneurs during 1991-2000 nearly one fourth (23 per cent) was for industrially developed Maharashtra, 17 per cent for Gujarat, 7 per cent for Andhra Pradesh, and about 6 per cent for Tamil Nadu while Uttar Pradesh, the state with the largest population has only 8 per cent.
- In spite of several concessions, seven north-eastern states could get less than 1 per cent of the proposed investment. In fact, economically weaker states could not compete with the developed states in the open market in attracting industrial investment proposals and hence they are likely to suffer from these processes.
9.5. Industrial Regions in India
- Industries are not evenly distributed in the country. They tend to concentrate on certain locations because of the favorable locational factors.
- Several indices are used to identify the clustering of industries, important among them are:
- the number of industrial units,
- number of industrial workers,
- quantum of power used for industrial purposes,
- total industrial output, and
- value added by manufacturing, etc.
9.5.1. Major industrial regions of the country
Mumbai-Pune Industrial Region
- It extends from Mumbai-Thane to Pune and in adjoining districts of Nashik and Solapur. Besides, industrial development has been rapid in Kolaba, Ahmednagar, Satara, Sangli and Jalgaon districts.
- Development of this region started with the location of the cotton textile industry in Mumbai. Mumbai, with a cotton hinterland and moist climate favoured the location of the cotton textile industry.
- Opening of the Suez Canal in 1869 provided impetus to the growth of Mumbai port. Machineries were imported through this port.
- Hydro-electricity was developed in the Western Ghat region to meet the requirements of this industry.
- With the development of the cotton textile industry, the chemical industry also developed.
- Opening of the Mumbai High petroleum field and erection of nuclear energy plants added additional pull to this region.
- Besides, engineering goods, petroleum refining, petrochemicals, leather, synthetic and plastic goods, drugs, fertilizers, electrical, shipbuilding, electronics, software, transport equipment and food industries also developed.
- Important industrial centres are Mumbai, Kolaba, Kalyan, Thane, Trombay, Pune, Pimpri, Nashik, Manmad, Solapur, Kolhapur, Ahmednagar, Satara and Sangli.
Hugli Industrial Region
- Located along the Hugli river, this region extends from Bansberia in the north to Birlanagar in the south for a distance of about 100 km. Industries also have developed in Medinipur in the west. Kolkata-Haora from the nucleus of this industrial region.
- Historical, geographical, economic and political factors have contributed much to its development. It developed with the opening of the river port on Hugli. Kolkata emerged as a leading centre of the country. Later, Kolkata was connected with interior parts by railway lines and road routes.
- Development of tea plantations in Assam and northern hills of West Bengal, the processing of indigo earlier and, jute later coupled with the opening of coalfields of the Damodar Valley and iron ore deposits of the Chotanagpur plateau, contributed to the industrial development of the region.
- Cheap labour available from the thickly populated part of Bihar, eastern Uttar Pradesh and Odisha also contributed to its development. Kolkata, being the capital city of British India (1773-1911), attracted the British capital.
- The establishment of the first jute mill at Rishra in 1855 ushered in the era of modern industrial clustering in this region. The major concentration of jute industry is at Haora and Bhatapara.
- The partition of the country in 1947 adversely affected this industrial region. Cotton textile industry also grew along with the jute industry, paper, engineering, textile machinery, electrical, chemical, pharmaceuticals, fertiliser and petrochemical industries have also developed within this region.
- The Hindustan Motors Limited factory at Konnagar and diesel engine factory at Chittaranjan are landmarks of this region. Location of petroleum refineries at Haldia has facilitated the development of a variety of industries.
- Important industrial centres of this region are Kolkata, Haora, Haldia, Serampore, Rishra, Shibpur, Naihati, Kakinara, Shamnagar, Titagarh, Sodepur, Budge Budge, Birlanagar, Bansberia, Belgurriah, Triveni, Hugli, Belur, etc. However, industrial growth of this region has slowed down in comparison to other regions. Decline of the jute industry is one of the reasons.
Bangalore-Chennai Industrial Region
- This region witnessed the most rapid industrial growth in the post-Independence period. Till 1960, industries were confined to Bangalore, Salem and Madurai districts but now they have spread over all the districts of Tamil Nadu except Viluppuram.
- Since this region is away from the coalfields, its development is dependent on the Pykara hydroelectric plant, which was built in 1932.
- Cotton textile industry was the first to take roots due to the presence of cotton growing areas. Along with cotton mills, the loom industry spread very rapidly.
- Several heavy engineering industries converged at Bangalore. Aircraft (HAL), machine tools, telephone (HTL) and Bharat Electronics are industrial landmarks of this region. Important industries are textiles, rail wagons, diesel engines, radio, light engineering goods, rubber goods, medicines, aluminium, sugar, cement, glass, paper, chemicals, film, cigarette, match box, leather goods, etc. Petroleum refinery at Chennai, iron and steel plant at Salem and fertiliser plants are recent developments.
Gujarat Industrial Region
- The nucleus of this region lies between Ahmedabad and Vadodara but this region extends upto Valsad and Surat in the south and to Jamnagar in the west. Development of this region is also associated with the location of the cotton textile industry since the 1860s.
- This region became an important textile region with the decline of the cotton textile industry at Mumbai. Located in a cotton growing area, this region has the double advantage of the proximity of raw materials as well as of the market.
- The discovery of oil fields led to the establishment of petrochemical industries around Ankleshwar, Vadodara and Jamnagar.
- The port at Kandla helped in the rapid growth of this region. Petroleum refinery at Koyali provided raw materials to a host of petrochemical industries.
- The industrial structure is now diversified. Besides, textiles (cotton, silk and synthetic fabrics) and petrochemical industries, other industries are heavy and basic chemicals, motor, tractor, diesel engines, textile machinery, engineering, pharmaceuticals, dyes, pesticides, sugar, dairy products and food processing. Recently, the largest petroleum refinery has been set up at Jamnagar.
- Important industrial centres of this region are Ahmedabad, Vadodara, Bharuch, Koyali, Anand, Khera, Surendranagar, Rajkot, Surat, Valsad and Jamnagar.
- This region extends over Jharkhand, northern Odisha and western West Bengal and is known for the heavy metallurgical industries.
- This region owes its development to the discovery of coal in the Damodar Valley and metallic and non-metallic minerals in Jharkhand and northern Odisha. Proximity to coal, iron ore and other minerals facilitated the location of heavy industries in this region.
