进口贸易技术溢出的地区差异及影响因素分析

应用LP方法测算中国30个省市自治区1998-2014年间从G7国家进口贸易中获得的技术溢出效应；运用熵值分析方法对全国、东中西部之间的进口贸易技术溢出差异进行分析；基于省际面板数据从吸收和引进两方面计量分析影响进口贸易技术溢出的因素。结果显示:进口贸易技术溢出效应在中国呈现出由东部向西部逐渐递减、空间分布集中度高的特点；从全国来看，研发强度、人力资本和贸易结构对中国进口贸易技术溢出起正向促进作用，技术差距起负向抑制作用；从区域来看，人力资本和技术差距在不同区域作用差异明显。其中，人力资本在东中部地区起正向作用，在西部地区起负向作用，技术差距在东部地区起促进作用，但不显著，在中西部地区起显著的负向作用。

Technology Spillover of Import Trade Regional Difference and Influencing Factors

This paper uses the method of LP to calculate the technology spillover effect of 30 provinces from the G7 countries over the period of 1998-2014,analyses the regional differences of technology spillover,and based on the provincial panel data from two aspects of absorption and the introduction of analysis of influence factors of technology spillover of import trade. The results show that:(1)The technology spillover effect of import trade in our country was gradually diminishing from east to west,the space distribution of highly concentration.(2)From a national perspective,R&D intensity,human capital and trade structure promoted technology spillover,and the technology gap was negative effects. (3)From a regional perspective,human capital and technology gap significantly effected in different regions,human capital played a positive role in the eastern and central regions,the negative effects in the western region,the technology gap played a positive role in the east,but not significant,since a significant negative effect in the Midwest.
