摘要: 保障房供应是否会对商品住房供应产生挤出效应,以及在何种情况下发生多大幅度的挤出效应,不仅关系到保障房工程的政策评估,也关系宏观经济稳定。本文从保障房最主要品种经济适用房入手,基于1999-2010年全国29个省份的面板数据,分别运用非线性门限面板模型、动态递归模型和GMM等分析方法来对我国经济适用房供应与纯商品住房供应之间的互动关系进行系统性研究。实证结果显示:(1)从住房销售面积及住宅投资额两个角度出发,经济适用房供应都对纯商品住宅供应产生了挤出效应;(2)挤出效应具有非线性,且根据经济适用房占住房总供应比重、与商品住房差异性等条件而存在“门槛效应”;(3)挤出效应不仅存在地区差异性,还会随着时间而变化,即挤出效应存在时间异质性。本文的研究结果对深入理解保障房的市场效应和完善相关政策设计提供了依据。

Abstract: This paper empirically examines how public housing provision affects the market-based housing provision in urban China. It is based on the provincial panel data for the period of 1999-2010 and special attention has been given to the potential nonlinear and heterogeneous pattern of the crowding effects. Our empirical result shows: (1) the supply of public housing crowded-out the supply of market housing but its degree was generally moderate; (2) the crowding-out effect varied substantially under different scenarios; (3) the degree of crowd-out effect changed over time but its sign was consistent in the sample period. These findings have important implications to help improving the design of public housing programs in general.
