The Nature of Secondary Activities
Secondary activities form the backbone of industrial development by adding value to natural resources.
All economic activities, from primary to quaternary, revolve around the utilization of resources for survival. Secondary activities specifically involve the transformation of raw materials into valuable products. For instance, cotton in its raw form has limited utility, but once processed into yarn, it becomes significantly more valuable and can be used to manufacture clothing.
Similarly, iron ore extracted from mines cannot be used directly. It must be converted into steel to gain value, which then allows for the production of machines and tools. This process of value addition applies to materials derived from farms, forests, mines, and the sea. Consequently, secondary activities are primarily concerned with manufacturing, processing, and construction industries.

Characteristics of Modern Manufacturing
Manufacturing is a complex process ranging from simple handicrafts to advanced aerospace assembly.
Modern large-scale manufacturing is defined by several key characteristics: the application of power, mass production of identical products, and specialized labour working in factory settings. While the literal meaning of manufacturing is 'to make by hand,' it now predominantly refers to goods made by machines.
A significant feature of modern industry is the specialisation of skills. In the traditional 'craft' method, factories produced few pieces made-to-order, resulting in high costs. In contrast, mass production involves workers performing a single repeated task to produce large quantities of standardised parts, which increases efficiency and lowers costs.
Evolution of Manufacturing Processes
- 1
Craft Method
Small-scale production of unique, made-to-order items with high per-unit costs.
- 2
Mechanisation
Introduction of gadgets and machinery to accomplish physical tasks previously done by hand.
- 3
Mass Production
Large-scale output of standardised parts using specialised labour and division of tasks.
- 4
Automation
Advanced stage where machines operate with computer control and minimal human intervention.
The transition from manual craft to fully automated industrial systems.

Factors Influencing Industrial Location
Industries are strategically located to maximise profits by minimising production and transport costs.
The most critical factor for industrial location is access to markets. A 'market' consists of people with both the demand and the purchasing power to buy goods. Developed regions like Europe and North America provide large global markets, while densely populated areas in South Asia also offer significant local demand. Some industries, such as aircraft manufacturing, have a global market and are not restricted by local consumer proximity.
Access to raw materials is another vital consideration. Industries using bulky or weight-losing materials, such as iron and steel or sugar, are located near the source of the raw material to reduce transport costs. Perishable goods, like dairy or agro-processed items, must also be processed close to their source.
Access to transportation and communication facilities is essential. Speedy transport moves raw materials to factories and finished goods to markets. Communication is equally important for the exchange and management of information. Furthermore, many industries benefit from 'agglomeration economies,' where nearness to a leader-industry and other industries creates savings through shared linkages.
Other factors include labour supply, energy sources, and government policy. While automation has reduced dependence on labour, some industries still require skilled workers. Power-intensive industries, like aluminium smelting, are located near energy sources. Governments also use regional policies to encourage industrial growth in specific areas for balanced economic development.
| Factor | Description | Example Industry/Region |
|---|---|---|
| Market Access | Proximity to consumers with purchasing power. | Developed regions of Europe/North America |
| Raw Materials | Nearness to cheap, bulky, or perishable inputs. | Steel, Sugar, Dairy |
| Energy Supply | Located near coal, hydro, or petroleum sources. | Aluminium |
| Transport | Efficient networks to move goods and materials. | Port-based industries |

Footloose Industries
Some industries possess the unique ability to locate in a wide variety of places regardless of raw material sources.
Footloose industries are not dependent on specific raw materials, whether weight-losing or otherwise. Instead, they rely on component parts that can be obtained from various locations. These industries typically produce in small quantities and employ a relatively small labour force.
A defining characteristic of footloose industries is that they are generally non-polluting. The primary factor determining their location is accessibility via road networks. Because their products are often high-value but low-bulk, the specific geography of raw materials does not restrict their placement.

Classification Based on Size
Industries are categorized by the capital invested, the number of workers, and the volume of production.
The size of an industry is determined by the amount of capital invested, the number of workers employed, and the volume of production. Based on these criteria, industries are classified into household or cottage, small-scale, and large-scale manufacturing.
Household or Cottage Manufacturing is the smallest unit. Artisans use local raw materials and simple tools to produce goods within their homes, often with family help. These products, such as pottery, mats, or simple tools, are for local consumption or barter and have low commercial significance.
Small Scale Manufacturing uses local raw materials and simple power-driven machinery. It is distinguished from cottage industry because production happens in a workshop outside the home. Countries like India and China promote this sector as it is labour-intensive and provides significant employment.
Large Scale Manufacturing involves massive markets, enormous energy requirements, advanced technology, and assembly-line production. This system requires vast capital and complex organisational structures. While it originated in the UK and USA over the last 200 years, it has now diffused globally.

Classification Based on Inputs and Raw Materials
Industries are often grouped by the type of raw materials they process.
Agro-based industries process materials from the field and farm, such as sugar, tea, coffee, and textiles. A modern extension of this is 'Agri-business,' which involves large-scale commercial farming financed by corporations. These 'agro-factories' are highly mechanised and reliant on chemicals.
Mineral-based industries use metallic or non-metallic minerals. Ferrous industries use iron, while non-ferrous ones use copper or aluminium. Chemical-based industries utilize natural minerals like salts, sulphur, and petroleum (petrochemicals), as well as synthetic fibres and plastics.
Forest-based industries rely on timber, bamboo, and grass for products like furniture and paper. Animal-based industries use leather and wool obtained from livestock to produce textiles and footwear. Additionally, ivory obtained from elephant's tusks is used as a raw material in this category.

Ownership and Output Classification
Industries can be classified by who owns them and what they produce.
Based on ownership, industries are divided into Public, Private, and Joint sectors. Public sector industries are government-owned (like PSUs in India), while private sector industries are owned by individual investors. Joint sector industries are managed by a combination of public and private interests.
Based on output, industries are classified as Basic or Consumer goods. Basic industries produce materials used by other industries; for example, the iron and steel industry provides the metal used to make machines for the textile industry. Consumer goods industries produce items for direct use by the public, such as bread, biscuits, soaps, and televisions.

High Technology Industry
High-tech represents the latest generation of manufacturing, driven by research and development.
High-tech industries are characterized by intensive Research and Development (R&D) and a workforce dominated by professional 'white-collar' specialists rather than 'blue-collar' production workers. Key features include robotics, Computer-Aided Design (CAD), and electronic controls.
The landscape of high-tech industry consists of neatly spaced, modern office-lab buildings rather than massive factories. When these industries concentrate in specific regions that are self-sustained and highly specialized, they are known as 'technopolies.' Famous examples include Silicon Valley near San Francisco and Silicon Forest near Seattle.
