中国电子商务发展对物流发展的贡献研究

Study on Contribution of E-commerce Development to Logistics in China

首先利用柯布—道格拉斯生产函数来构建物流产出模型,再利用曲线回归的方法,通过考核曲线的斜率变化,来研究不同时期电子商务对物流发展的贡献。得出电子商务对物流发展的贡献出现了拐点,正由正向影响向负面影响发展,其主要原因是对物流建设的投入不足。

In this paper, first we established the logistics output model by applying the Cobb-Douglas production function. Then through the nonlinear regression method to assess the change of a curve＇s slope, we analyzed the contribution of e-commerce to the logistics develop- ment in different times. Hence we concluded that there was an inflection point in the slope, which meant the positive influence of e-commerce to the logistics development had gradually turned into negative due to the insufficient investment om logistics construction.
