中国经济发展省际差距成因的双层挖掘分析

循着要素规模、质量和效率三位一体的逻辑，从两个层次挖掘区域之间经济差距形成及其变迁的驱动因素，引入可导性对数方差分解法的基本原理，构造了区域间经济差距形成及其变迁的驱动因素贡献的双层分解模型，并利用中国31个省份2005-2012年数据进行实证分析。结果表明，省际经济差距形成和绝对差距扩大的首要推动力是全要素生产率差距，人均资本差距也起到了较大的贡献作用；在全要素生产率差距贡献中，综合效率差距提供了主导性的正向支持，高级人力资本占比差距也具有较大的推动作用，而设备性资本占比差距起到显著的抑制作用。

Double-Level Excavating Analysis of China's Inter-Provincial Gaps of Economic Development

Following the trinity logic of the organic unity of three elements of size, quality and efficiency, this study seeks to excavate the driving forces and change of economic gaps between regions from two levels. It introduces the basic principles of conductivity variance decomposition method into the analysis, and constructs a double decomposition model of contribution of driving forces of the formation of regional economic disparities and their change. It employs the data of the 31 provinces in China from 2005 to 2012 to test the model. The results show that the primary driver of the formation of inter-provincial economic disparities and absolute disparity is the total factor productivity gap, and that the per capita capital also plays a great role in it. They also show that among the contribution to the total factor productivity gap, the overall efficiency gap provides a dominant positive energy, the disparity of proportion of advanced human capital accounts for a great role in promoting the gap, and the disparity of proportion of equipment capital plays a significant inhibitory effect.
