Indian Economy is a foundational topic for TNPSC Group IV. Questions typically test your understanding of economic terminology, planning bodies, banking institutions, tax systems, and welfare schemes. The syllabus expects SSLC-level knowledge, so focus on definitions, functions of key institutions, and flagship government programmes rather than complex economic theories.

Key ideas

• Mixed Economy: India follows a mixed economic system where both public sector (government-owned enterprises) and private sector coexist. The government controls strategic sectors like defence, railways, and atomic energy while private enterprise operates in most other areas.
• Three Sectors of Economy: Primary sector (agriculture, mining, fishing), Secondary sector (manufacturing, construction), and Tertiary sector (services like banking, IT, transport). India's GDP is now dominated by the tertiary sector, though agriculture employs the largest workforce.
• Economic Planning: Systematic allocation of resources to achieve development goals. India adopted Five-Year Plans from 1951 under the Planning Commission, now replaced by NITI Aayog since 2015.
• Gross Domestic Product (GDP): Total value of all goods and services produced within the country in a year. It measures economic growth and is calculated by the Ministry of Statistics and Programme Implementation.
• Inflation: Sustained increase in general price levels, reducing purchasing power. Measured by Consumer Price Index (CPI) for retail inflation and Wholesale Price Index (WPI) for wholesale inflation.

Watch out for

• Confusing Planning Commission with NITI Aayog: Students think NITI Aayog also creates Five-Year Plans. Correction: NITI Aayog prepares 15-year Vision Documents and 7-year strategies, not Five-Year Plans. Planning Commission was a non-statutory body with plan allocation powers;
• Mixing up CPI and WPI: Believing both measure the same thing. Correction: CPI measures retail prices affecting consumers (used for inflation targeting by RBI). WPI measures wholesale/bulk prices between businesses.
• Assuming GST replaced all taxes: Thinking GST covers everything. Correction: GST does not include petroleum products (petrol, diesel), alcohol for human consumption, and electricity—these remain outside GST (petrol and diesel still attract central excise duty as well as state VAT).

Quick reference

• India = Mixed Economy (public + private sectors coexist)
• NITI Aayog replaced Planning Commission on 1 January 2015
• RBI: Central bank, controls monetary policy, regulates banks
• GST: Indirect tax since July 2017, subsumed 17 central/state taxes
• Three sectors: Primary (agriculture), Secondary (industry), Tertiary (services)
