ECX2630 Chap.4 Income Distribution in China
Income Distribution in China
Keep two geographic divides visible
China's distribution story contains both an urban-rural divide and an inland-coastal divide. The first connects to sector productivity, migration, household registration and access to education or health. The second connects to the geography of opening, foreign investment, infrastructure and export access.
They can move in different directions, which is why one national inequality statistic cannot reveal the mechanism.
Distinguish deprivation from relative position
An absolute poverty threshold asks whether resources meet a defined minimum. Relative poverty locates households inside the current distribution. Growth can move many households above an absolute threshold while income at the top grows faster.
That result is not contradictory. The indicators answer different questions.
Design policy from diagnosis
Service portability addresses a different barrier from inland logistics. Fiscal transfers address immediate resources but may not change productivity or access. Education, health and transport can support both equity and efficiency, though benefits depend on who can use them.
A strong policy paragraph identifies the barrier, instrument, predicted response, distributional incidence and evidence needed to monitor implementation.

Key terms
- Absolute Poverty
- Absolute poverty compares resources with a defined minimum intended to represent basic needs rather than a household's position inside the current distribution.
- Relative Poverty
- Relative poverty compares income with a contemporary social benchmark and therefore captures position and inequality as well as material resources.
- Lorenz Curve
- A Lorenz curve plots the cumulative share of income received by cumulative shares of the population to display distributional concentration.
- Gini Coefficient
- The Gini coefficient summarises inequality from the Lorenz distribution but does not identify the institutions or regions causing the observed pattern.
- Household Registration
- Household registration is an administrative system connecting residence status with access to services and mobility, influencing urban-rural opportunity.
- Regional Disparity
- Regional disparity is an uneven distribution of income, productivity, infrastructure or access across geographic areas such as coastal and inland regions.
Income Distribution in China FAQ
What is the difference between absolute and relative poverty?
Absolute poverty uses a defined minimum standard, while relative poverty compares households with the current income distribution. One can fall while inequality widens because they measure different aspects of economic wellbeing.
Why are there two major geographic inequality stories?
Urban-rural differences involve sectors, mobility and service access, while inland-coastal differences reflect the geography of opening, infrastructure, foreign investment and export opportunity. The mechanisms overlap but are not interchangeable.
Can the Gini coefficient explain why inequality changed?
No. It summarises the distribution and direction, but causal explanation requires evidence on labour markets, household registration, sector productivity, public services, investment geography and other institutions that generate the pattern.
How should I evaluate an inequality policy?
State the objective, identify the barrier, show who can access the intervention and predict the behavioural response. Then monitor both average outcomes and distribution across the intended groups to detect capture or exclusion.
Assessment move
Draw a two-axis map with urban-rural on one dimension and inland-coastal on the other. Place each policy beside the barrier it targets. Practise interpreting three indicators that move in different directions without forcing one overall label. In every recommendation, include distributional incidence: who pays, who receives, who can participate and which group may be unintentionally excluded.
Keep outcome inequality, opportunity inequality and poverty on separate revision cards, because one can improve while another worsens. For each statistic, record its unit, coverage, period and sensitivity to prices or migration.
Build a mechanism chain from household registration, fiscal capacity, education, transport or industrial geography to access, productivity and income; then identify one observation that would distinguish that channel from a simple coastal-growth story. When evaluating regional policy, separate immediate redistribution from durable capability and market access.
Practise a two-policy comparison using targeting, incentives, administrative capacity and unintended exclusion as criteria. In a timed response, define the divide first, diagnose the barrier second and recommend only after that diagnosis. End by stating whose welfare changes, over what horizon, and what monitoring result would count as failure.
