人口地理与公共品供给效率——以四川省135个县(市)为例

Population,Geography and the Efficiency of Local Public Goods Supply:The Empirical Evidence from 135 Counties in Sichuan Province

利用四川省135个县(市)的数据,分析人口、地理因素对县(市)公共品供给效率的影响。研究发现,2008年135个县(市)平均公共品供给效率为0.672,整体水平还有待进一步提高;县(市)辖区人口密度的提高、所辖乡镇数量的增加有助于供给效率提高;复杂的地理环境增加了公共品提供成本,降低了供给效率;乡镇辖区面积扩大及人口增加有助于供给效率的提高。研究对提高地方公共品供给效率,完善地方政府及财政层级改革颇具参考价值和意义。

Using 135 counties and cities in Sichuan province,this paper positively analyzes the impact of population and geography factors on the supply efficiency of local public goods.The empirical results are as follows.The average efficiency of sample counties is 0.672,still not high,has a big space of improvement.Increasing the population density and township＇s number of county is helpful to the efficient provision of local public goods;complex terrain and geography raises the cost of public goods provision,reduces the efficiency of local public goods supply;the expanding of acreage and population scale which the jurisdiction is township,will contribute to enhancing the efficiency of public goods supply.The research conclusions are valuable not only in the improvement of local public goods provision efficiency,but also in the reform of local government and fiscal level.
