财政分权与市场整合对工业用地利用效率影响的异质性研究

Study on Heterogeneous Effects of Market Integration on the Utilization Efficiency of Industrial Land under the Background of Fiscal Decentralization

本文利用2005-2017年省际面板数据,运用SBM-DEA模型测算中国30省份(西藏地区和港澳台地区因数据缺失而剔除)工业用地利用效率。随后,构建面板分位数回归模型,研究财政分权与市场整合在不同分位点处对工业用地利用效率的异质性影响。研究发现:第一,当工业用地利用效率较低时(0.1~0.3分位点处),财政分权对工业用地利用效率具有显著的负向影响(影响系数为-0.6402^-0.1998);而随着分位点提升(0.4~0.9分位点处),财政分权对工业用地利用效率将产生正向促进作用(影响系数为0.2301~0.7150);财政分权对工业用地利用效率增长率的影响随着分位点提高大致呈倒"U"型变化趋势。第二,随着分位点的提高,市场整合对工业用地利用效率增长的贡献趋于平稳,对工业用地利用效率增长率的正向促进则逐渐减弱。第三,财政分权与市场整合的共同作用在低分位点处对工业用地利用效率及其增长率具有负向影响(对工业用地利用效率的影响系数为-0.0294^-0.0088;对工业用地利用效率增长率的影响系数为-0.2635^-0.2838),在高分位点处则会产生正向促进作用(对工业用地利用效率的影响系数为0.0042~0.0540;对工业用地利用效率增长率的影响系数为0.2004~1.1496)。

Based on the inter-provincial panel data from 2005 to 2017,this paper constructs a panel quantile regression model to study the heterogeneous effects of fiscal decentralization and market integration on the utilization efficiency of industrial land at different quantiles.The study finds that:Firstly,when the utilization efficiency of industrial land is low(in the 0. 1~0. 3 quantiles),fiscal decentralization has a significant negative impact on the utilization efficiency of industrial land(the impact coefficient is-0. 6402^-0. 1998). However,as the quantile increases(in the 0. 4~0. 9 quantiles),fiscal decentralization has a positive effect on the utilization efficiency of industrial land(the impact coefficient is 0. 2301~0. 7150). The impact of fiscal decentralization on the growth rate of industrial land use efficiency has shown an inverted u-shaped trend with the increase of the quantile. Secondly,Market integration plays a positive role in promoting industrial land use efficiency and its growth rate. The contribution of market integration to the growth rate of industrial land use efficiency tends to be stable with the increase of the quantile point,while the positive contribution to the growth rate of industrial land use efficiency gradually weakens. Thirdly,the combined effect of fiscal decentralization and market integration has a negative impact on industrial land use efficiency and its growth rate at low points(the influence coefficient on the utilization efficiency of industrial land is-0. 0294^-0. 0088. The influence coefficient on the growth rate of industrial land use efficiency is-0. 2635^-0. 2838),and positive promotion at high points(the influence coefficient on the utilization efficiency of industrial land is 0. 0042~0. 0540. The influence coefficient on the growth rate of industrial land use efficiency is 0. 2004~1. 1496).
