National Income and Economic Planning — UPSC Indian Economy Notes Ch. 2

Introduction

National income accounting provides the vocabulary for measuring an economy's size and growth, while India's planning history — from the Planning Commission's Five Year Plans to NITI Aayog's more flexible approach — reflects the country's evolving development philosophy.

National Income Concepts

Concept	Definition
GDP (Gross Domestic Product)	Total value of final goods and services produced within a country's territorial boundaries in a year
GNP (Gross National Product)	GDP + Net Factor Income from Abroad (NFIA) — income earned by residents abroad minus income earned domestically by non-residents
NDP (Net Domestic Product)	GDP minus Depreciation (wear and tear of capital)
NNP (Net National Product) / National Income	GNP minus Depreciation — considered the most refined measure of a nation's income
Per Capita Income	National Income divided by total population

💡 Real vs Nominal GDP: Nominal GDP is measured at current market prices (includes inflation); Real GDP is measured at constant prices (adjusted for inflation) — Real GDP growth is the figure typically used to measure actual economic growth.

Methods of Measuring National Income

Flowchart — Three Approaches to Measuring GDP

Production (Value Added) Method — sum of value added at each stage of production

Income Method — sum of all factor incomes (wages, rent, interest, profit)

Expenditure Method — sum of all spending (consumption + investment + government spending + net exports)

All three methods should theoretically yield the same GDP figure, since one person's expenditure is another's income, which in turn reflects value added in production.

In India, GDP is compiled by the National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation (MoSPI), using base-year price references that are periodically updated (the current base year is 2011-12).

Evolution of Economic Planning in India

Plan/Period	Key Focus
First Five Year Plan (1951-56)	Agriculture — based on the Harrod-Domar growth model
Second Five Year Plan (1956-61)	Rapid industrialisation — the "Mahalanobis Model," emphasis on heavy/basic industries
Third Plan onward	Various shifting priorities — self-reliance, poverty alleviation ("Garibi Hatao" era plans), and later liberalisation-era plans post-1991
Twelfth Plan (2012-17)	Last Five Year Plan — "Faster, More Inclusive and Sustainable Growth"

Planning Commission → NITI Aayog

Flowchart — Institutional Transition

Planning Commission (1950-2014) — non-statutory body, formulated centralised Five Year Plans

↓

Replaced by NITI Aayog (National Institution for Transforming India), 2015 — also non-statutory

↓

Shift from top-down 5-year plans to more flexible, longer-term Vision/Strategy/Action-Plan documents and a "cooperative-competitive federalism" model, giving states greater voice

NITI Aayog functions primarily as a policy think tank — it does not allocate plan funds to states/ministries the way the Planning Commission did (that function shifted to the Finance Ministry). Its Governing Council includes all Chief Ministers, reflecting its cooperative-federalism design.
