土地规制度量及其对住宅用地价格的影响

Measuring Land-use Regulation and Its Effect on Residential Land Price

近年来地价持续上涨引发了学者们的广泛关注和深入研究,不同于以往基于需求侧的研究,本文试图从供给侧的土地规制角度探究中国房价居高不下的原因并提供政策建议。本文利用中国35个主要城市2007-2016年共31939笔住宅用地交易数据,同时选取多个规制因子全方位度量地方土地规制程度,并通过无量纲法构建出中国城市土地规制程度综合指标(LURIC),考察土地规制程度对住宅用地价格的影响。研究发现:东部规制强度最大,中西部较小。土地规制程度越高,该地区住宅用地的价格越高;城市规模越大,土地规制的影响越显著。

This paper empirically examines the reason of price soaring in urban China from the perspective of supply-side.A database of 31,939 urban land market transactions across 35 major cities from 2007-2016,together with an indicator of land-use regulation index of China(LURIC)-a new measure of the local regulatory environment for land market,allow us to assess factors underlying LURIC and their impact on residential land price.The results show that,(1)on average,the degree of land-use regulation in the eastern region is highest,followed by the central and western region;(2)the land use regulation significantly drives up the residential land price;(3)the effect of land use regulation would be higher in the places where the city size is relatively large.
