摘要
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。
We constructed a model to establish the connection between logistics performance and technological sophistication of the export sector within a firm heterogeneity framework. Using HS-4 digital trade data from 2002-2011 and the methods developed by Hausmann et al.(2007), we measured 30 Chinese provinces with an export technological sophistication index and empirically test for the determinants of a province's measurement in the index. The results strongly support the predictions of the theoretical model. Our research also shows that RD, the import trade, FDI, human capital, and the ratios of capital and labor play a positive role on the growth of sophistication in this area.
