要素市场扭曲、区域差异与R&D投入

本文利用要素市场扭曲指数及中国高技术产业1997～2009年省际面板数据，考察了要素市场扭曲对R&D投入的影响及区域差异。结果表明，要素市场扭曲对R&D资本投入和R&D人力投入有着不同的影响，抑制了R&D资本投入增长，促进了R&D人力投入；而且其对两者的影响都存在着显著的区域差异。在此基础上，运用门槛检验方法对这种区域差异的影响因素进行了探讨，研究发现，在区域经济发展水平、人力资本水平、财政收入、产权结构和对外开放程度等因素的不同门槛值区间，要素市场扭曲对高技术产业R&D投入的影响程度和方向都存在着明显的差异。

Factor Market Distortion, Regional Differences and R&D Input

This article utilizes the index of factor market distortion and the inter-provincial panel data of China's high-tech industries during the period of 1997~2009 to make an empirical study how factors market distortions influence the R&D input. The results show that factor market distortion has significantly different effects on R&D capital investment and R&D human resources input. It has an negetive impact on the R&D capital investment, but promotes R&D human resources input. Moreover, there are regional differences of factors market distortions influence on the R&D input. Based on these, the paper uses threshold methods to explore the factors of the regional differences. The results show that the degree and direction are obvious differences, when the factors such as regional economic development and human capital and financial income and equity structure and openness are in different threshold intervals.
