我国经济增长与土地违法的Kuznets曲线分布与治理研究——基于2001-2011年省际数据的检验
Study on Kuznets Curve Distribution and Governance of China’s Economic Growth and Land Illegality——Based on Test of Inter-provincial Data between 2001 and 2011

基于2001-2011年省级面板数据和时间序列数据，从全国层面和省级层面分析我国经济增长与土地违法之间的库兹涅茨曲线效应与其拐点分布。结果显示：我国经济增长与土地违法之间存在显著的库兹涅茨曲线特征，但在省级层面，除江苏、河南、新疆等3个省份表现为显著正相关以外，其他省份尚未拟合成库兹涅茨曲线；政府干预能改变库兹涅茨曲线的拐点值，如通过土地督察可加大土地违法成本，减少其涉案面积，降低其对经济增长带来的影响。土地督察制度改革的方向应推动土地督察立法，完善土地督察联动机制，并对土地督察机构工作人员形成激励约束机制，避免产生委托代理问题。
Based on provincial panel data and time series data from 2001 to 2011,this paper analyzes the Kuznets curve effect and its inflection point distribution between economic growth and land illegality from both the national level and provincial level.The result shows that there is a significant feature of Kuznets curve between China's economic growth and land illegality.However,from the provincial level,except that three provinces like Jiangsu,Henan,Xinjiang showed a significant positive correlation,the other provinces have not yet proposed synthetic Kuznets curve,which indicates that government intervention can change the Kuznets curve inflection point value.,for example,the cost of land illegality could be increased,land illegality illegal land areas involved could be reduced,and the impact of land illegality on economic growth could also be reduced through government intervention.To avoid the principal-agent problems,reform of land inspectors should focus on the promotion of land inspector legislation,improvement of land inspectors linkage mechanism,and the formation of incentive and restraint mechanisms among land inspection staffs.
