本文在企业异质性框架下,从理论上分析了物流发展对出口技术复杂度的影响机制。在此基础上,采用2002~2011年我国30个省份的面板数据,借鉴Hausmann et al.(2007)的方法,测算了各省的出口技术复杂度指数,并对一地区物流发展影响其出口技术复杂度的理论机制进行了实证研究。计量结果表明,物流发展对提升出口技术复杂度具有稳健、显著的促进作用。此外,研发支出、进口贸易、外商直接投资、人力资本和人均物质资本等因素对出口技术复杂度也有着积极的作用。
Under the framework of enterprise heterogeneity, this paper theoretically analyzes the mechanism of the impact of logistics development on the technical complexity of exports. On this basis, using the panel data of 30 provinces in our country from 2002 to 2011, we draw on the method of Hausmann et al. (2007) to calculate the export technical complexity index of each province and influence the export technology complexity of a region’s logistics development Degree of theoretical mechanisms for empirical research. The measurement results show that the development of logistics has a steady and significant role in promoting the technical complexity of export. In addition, such factors as R & D expenditure, import trade, foreign direct investment, human capital and per capita material capital also play a positive role in the technical complexity of exports.
