土地出让方式对空气质量的影响分析
Analysis on the Influence of Land Leasing Mode on Air Quality

探讨土地出让方式对空气质量的影响对完善土地利用政策及环境治理有重要意义。本文基于2004~2017年省级面板数据，通过构建空间杜宾模型分析不同的土地出让方式对空气质量的影响。研究发现：虽然协议出让和招拍挂出让方式对SO₂排放量均具有显著的正向影响，但是协议出让的直接效应大于招拍挂出让方式；协议和招拍挂出让的间接效应均大于直接效应，说明招商引资可能存在“逐底竞争”现象。
Discussing the influence of land leasing mode on air quality is of great significance to improve land use policies and environmental governance. Based on the provincial panel data from 2004 to 2017 in China, this paper analyzes the influence of different land leasing mode on air quality by adopting a spatial Dubin model. The results are as follows: although both the agreement leasing and the bidding, auction and listing leasing mode have a significantly positive effect on SO₂ emissions, the direct effect of the agreement leasing is greater than the bidding, auction and listing leasing mode; the indirect effects of the agreement and the bidding, auction and listing leasing are both greater than the direct effects, which shows that there may be a phenomenon of “race to the bottom” in attracting investment.
