人力资本、创新投入与民营高新技术产业增长关系研究——基于中国省际面板数据的实证分析
Research on the Relationship between Human Capital，Innovation Input and the Growth of Private Hi-tech Industry——Empirical Analysis Based on Provincial Panel Data in China

摘要 走转变方式、优化结构、转换动能的高新发展道路已经成为实现经济新常态增长和供给侧改革的必然选择。选取2007－2016年中国省际面板数据，利用扩展的Solow模型，采用两步系统GMM估计方法，分别从全国层面和区域层面分析影响民营高新技术产业增长的关键要素具有重要的经济和现实意义。实证研究发现：全国层面，人力资本要素对民营高新技术产业经济增长的贡献率为8%，而创新投入的贡献率也仅为11%；区域层面，无论是人力资本要素还是创新投入要素，其经济效率主要表现在东部地区，产出弹性分别为0.17和0.31，而在中西部地区二者贡献较小甚至不显著，传统生产要素如物质资本存量、劳动力数量在中部和西部地区成为民营高新技术产业增长的主要驱动力量。
Abstract：Taking the development path of transforming the mode，optimizing the structure，and converting the kinetic energy，has become the inevitable choice for realizing the new normal economic growth and supply-side reform. Choosing China’s provincial panel data from 2007 to 2016 and using the extended Solow model and the two-step system GMM estimation method to analyze the key elements influencing the growth of private high-tech industries at national and regional levels respectively， has important economic and practical significance. Empirical studies found that at the national level， the contribution rate of human capital to the economic growth of private high-tech industries is only 8%， also the innovation investment is only 11%；At the regional level，whether it is the human capital factor or the innovation input factor， its economic efficiency is mainly reflected in the eastern region，and the output elasticity is 0.17 and 0.31，while， in the central and western regions，the contribution of the two is small or not significant.The traditional production factors——physical capital stock and the number of labor——in the central and western regions have become the main driving forces for the growth of private high-tech industries.
