官产学R&D合作、知识溢出与区域专利创新产出

An empirical analysis of R&D cooperation and regional knowledge spillovers based on knowledge production function

"官产学"R&D合作、知识溢出与区域专利创新产出的关系研究不仅是一个重要的学术问题,而且具有重要的政策含义。本文以2000-2006年中国大陆31个省级区域为空间样本,基于改进的知识生产函数,对以专利创新产出和R&D经费投入衡量的区域R&D合作与知识溢出进行了截面计量分析。经验估计结果显示,我国各个地区的企业自身R&D经费投入对专利产出的作用明显但不稳健;大学研究对企业创新产出具有明显而稳定的知识溢出效应;政府直接对企业进行R&D支持对企业专利创新产出并不是一种有效的制度安排;在政府引导下的产学R&D合作不论对企业还是大学均为一种良好的制度安排,是促进我国专利创新产出的一条有效途径。

The study on cooperation of ＂university -industry -government＂ and regional knowledge spillovers is not only an important academic problem, but also has an important policy implication. By way of the spatial samples of Chinese 31 provincial regions in the Chinese mainland and employing cross - sectional data of 2003 - 2005, based on the improved knowledge production function for the first time, the paper analyses the regional R＆D cooperation and knowledge spillovers cross - sectionally using variables of patent inno- vation and R＆D expenditure investment. The empirical estimation results show that though the regional impact of R＆D expenditure in- vestment on enterprise patent output is not so obvious and robust, the impact of university R＆D investment on enterprise innovation spillovers is not obvious and robust also and furthermore,to the firm ＇ s patent innovation, the dual cooperation between enterprise and government is not an effective institutional arrangement, whereas it is a favorable institutional arrangement for firm or university under the government＇s leading industrial -university cooperation and it is effective route to promote the patent innovation output. In addi- tion, it also shows that firm size （absorptive capacity） exerts an obvious and positive impact on regional patent innovation.
