Lifelines of National Economy — NCERT Solutions

Trade refers to the exchange (buying and selling) of goods and services between individuals, regions, or countries.

Difference between International and Local Trade:

Local trade is conducted within a limited area, while international trade crosses national boundaries.

Given: The role of transportation and communication in a nation's economy.

Answer:

Means of transportation and communication are called the lifelines of a nation and its economy because of the following reasons:

1. Movement of goods and people: Transportation networks (roads, railways, airways, waterways) carry raw materials from production centres to factories and finished goods from factories to markets. Without this, economic activity would come to a standstill.

2. Integration of markets: They link different regions of the country, integrating local, regional, and national markets. This ensures that goods produced in one part of the country are available in other parts.

3. Agricultural and industrial development: Farmers can sell their produce in distant markets, and industries can obtain raw materials from far-off places, boosting both agricultural and industrial growth.

4. Employment generation: The transport and communication sector itself provides employment to millions of people.

5. National unity and security: Roads and railways connect remote border areas with the mainland, strengthening national integration and enabling quick movement of defence forces.

6. Communication networks (telephone, internet, postal services) facilitate the exchange of information, enabling trade, governance, and social interaction.

Thus, just as blood vessels are lifelines of the human body, transportation and communication networks are the lifelines of a nation and its economy.

Given: Changes in international trade over the last fifteen years.

Answer:

International trade refers to the exchange of goods and services between countries. The nature of India's international trade has changed significantly in recent years:

1. Shift from raw materials to manufactured goods: Earlier, India mainly exported raw materials and agricultural products. Now, India exports a large variety of manufactured goods, engineering products, software, and services.

2. Growth of service sector exports: India has emerged as a major exporter of IT services, business process outsourcing (BPO), and software. This has transformed the composition of exports.

3. Diversification of trading partners: India's trade is no longer limited to a few countries. It now trades with a large number of countries across Asia, Europe, America, and Africa.

4. Increase in volume: The total volume of India's international trade has grown enormously due to liberalisation and globalisation policies adopted since 1991.

5. Rise of sea ports and airports: Modern ports like Jawaharlal Nehru Port (Mumbai) and airports have been developed to handle the increased volume of international trade.

6. Trade balance: India imports more than it exports in goods (trade deficit), but earns significantly through service exports and remittances.

Thus, international trade has become more diversified, technology-driven, and larger in volume, playing a crucial role in India's economic growth.
