高技术产业的企业规模质量、技术创新效率及区域差异的门槛效应

Research on the Threshold Effect between Firm Size Quality and Technological Innovation Efficiency:Panel Data from High-tech Industries in China

本文基于我国高技术产业2003-2013稳步发展阶段的省际面板数据,采用DEA-Malmquist指数分析法生成技术创新效率变量,并采用因子分析法将R&D投入、非R&D投入以及知识能量降维为企业规模质量变量,实证检验了中国高技术产业的企业规模质量对技术创新效率的门槛效应。实证检验得到以下主要结论:首先,我国高技术产业的技术创新效率呈现明显的区域差异,中部地区最高,西部地区次之,东部地区最后,技术进步是导致各区域技术创新效率低的主要原因。其次,高技术产业的企业规模质量与技术创新效率之间存在明显的门槛效应,满足三重门槛回归模型。最后,企业规模质量对技术创新效率的影响力度整体上呈正相关关系,在不同的企业规模质量门槛区间内有不同程度的影响力,且政府扶持对技术创新效率并非完全具有正向作用。

This study is based on a threshold regression model of panel data of 27 provinces on high-tech industries in China from 2003 to 2013 and examines the threshold effect of firm size quality on technological innovation efficiency. Before that, the paper utilizes Malmquist index method based on DEA to disaggregate, evaluates and tests the technological innovation efficiency. Then the paper reduces dimensionality of the R＆D investment, non-R＆D investment and knowledge energy into firm size quality with Factor Analysis. Finally, the paper examines the threshold effect of firm size quality on technological innovation efficiency. The research finds out that there exists a threshold effect of firm size quality on technological innovation efficiency. Moreover, different firm size quality intervals are shown to have different roles and influences on technological innovation efficiency. And triple thresholds effect of firm size quality on technological innovation efficiency respectively represent the improvement of R＆D investment, non-R＆D investment and knowledge energy, which proves the rationality of components of firm size quality. Thus, presenting concrete proposals to meet the China＇ s firm size quality adjustments. And it provides theoretical guidance in order to improve our country＇ s regional technological innovation ability of our country.
