区域经济发展质量的影响因素研究*--基于城乡收入差距的视角

摘要

This paper uses the panel data of Jiangxi Province,which include 81 counties from year 1989 to 2011,to study the influencing factors of urbanGrural income difference.This study found that:First,The development of education,the implementation of the newer rural cooperative medical and retirement security and other social security policy do not reduce the income difference between urban and rural areas, but to further expand the urbanGrural income difference;Second, Economic geography has a significant impact on narrowing the income difference,such as whether a county belongs to the Poyang Lake Ecological Economic Zone or not;Third,To increase the farmers'cultivated land per capita,irrigated area per capita and sown area per capita of farm crops that can notably decrease the urbanGrural income difference ;Finally,power of agricultural machinery per capita is positively related with urbanGrural income difference, because it reflected the level of agricultural modernization.Our result shows that the level of agricultural modernization does not necessarily reduce the income urbanGrural income difference.%城乡收入差距的大小关系到区域经济发展质量的高低。使用1989-2011年江西省81个县(市)的面板数据，从城乡收入差距的角度，研究了江西县域经济发展质量的影响因素。与现有的研究不同，研究发现：(1)教育扩展、农村合作医疗保险与养老保险等社会保障政策的实施不仅没有减少城乡收入差距，反而进一步扩大了城乡收入差距；(2)经济地理因素，如是否属于鄱阳湖生态经济区等会对城乡收入差距产生显著影响；(3)农民人均耕地面积、人均有效灌溉面积和人均农作物播种面积的提高，可以显著降低城乡收入差距；(4)农民人均农用机械总动力与城乡收入差距呈正相关，由于农用机械总动力反映的是农业现代化水平的高低，实证结果表明农业现代化水平的提升并不一定能缩小城乡收入差距。此外，研究还发现区域金融发展并没有像理论预期那样能够减少城乡收入差距，其对城乡收入差距的影响是不确定的。
