Housing Costs and Real Income Differences across Chinese Cities

主讲人:Sylvie Démurger教授,法国国家科学研究中心

主持人:李实,浙江大学文科资深教授、共享与发展研究院院长

摘要:我们记录了中国各城市中高技能家庭、低技能家庭以及农村外来务工家庭实际收入的差异。通过运用关于地块交易的综合数据,以及有关土地开发和家庭支出的个体数据,我们构建了一个特定城市住房成本指数,并评估了该指数在不同地区之间的差异情况。正如理论所预测的那样,住房成本的三个组成部分 —— 单位土地价格、土地在建筑成本中的占比以及住房在支出中的占比 —— 从城市中心到城市周边逐渐降低,随城市人口数量的增加而上升,并随城市土地面积的增加而减少。总体而言,中国的住房成本较高,且在不同地区之间差异很大。虽然从小城市迁移到大城市时,收入的增加超过了住房成本的增长,但在最大的城市中,住房成本开始占据主导地位,尤其是对于低技能和农村外来务工家庭来说。这表明在中国,实际收入与城市人口之间存在一种钟形关系,这与理论预测是相符的。

Abstract: We document variations in real income for high-skilled, low-skilled, and rural migrant households across Chinese cities. Using comprehensive data on land parcel transactions along with individual data for land development and household expenditure, we construct a city-specific housing cost index and assess how it varies across locations. All three components of housing costs unit land prices, land share in construction, and housing share in expenditure decrease from city centres to the periphery, increase with city population, and decrease with city land area, as predicted by theory. Overall, housing costs in China are high and vary widely between locations. While income gains outweigh housing costs when moving from smaller to larger cities, in the largest cities, housing costs begin to dominate, particularly for low-skilled and rural migrant households. This suggests a bell-shaped relationship between real income and city population in China, aligning with theoretical predictions.


主讲人简介

Sylvie Démurger是法国国家科学研究中心(CNRS)教授,担任法国里昂高等师范学院治理、不平等与冲突经济研究中心(CERGIC)副主任。她也是波恩IZA的研究员和欧洲研究发展网络(EUDN)的成员。她拥有法国巴黎第一大学经济学博士学位。她的主要研究领域是应用微观经济学,尤其是长期关注中国经济问题。在Journal of Development Economics, European Economics Review, Economic Development and Cultural Change, World Development 以及《经济研究》、《管理世界》、《经济学(季刊)》等国内外权威期刊上发表了多篇与中国经济与社会发展相关的问题。她最近的研究探索了接受或规范市场机制的公共政策对再分配的影响。她同时关注中国国内人口流动的动态及其与城乡发展的关系,旨在理解劳动力流动如何影响中国的不平等模式。

Sylvie Démurger is a CNRS Professor affiliated with the Center for Economic Research on Governance, Inequality and Conflict (CERGIC) and the Department of Economics at Ecole Normale Supérieure de Lyon (France). She is also a Research Fellow at IZA (Bonn) and a member of the European Research Development Network (EUDN). She holds a PhD in economics from the University of Paris 1 Panthéon-Sorbonne (France).

Her primary research area is applied microeconomics, with a particular focus on economic development in China. Her recent work explores the redistributive consequences of public policies that either embrace or regulate market mechanisms. She is also interested in the dynamics of internal migration and its relationship with urban and rural development, aiming to understand how labor mobility shapes patterns of inequality in China.
