转型经济下研发强度对利用式创新和探索式创新的影响研究

Study on the Effect of R&D Intensity on Exploitative and Exploratory Innovation Based on Transitional Economy

采用568家中国主板上市公司2007-2010年的专利和财务数据进行负二项回归,实证检验了研发强度对企业双元创新的影响,并且探索中国转型经济情境下制度逻辑对研发强度与企业双元创新关系的解释。结果显示：研发强度对利用式创新和探索式创新都会产生正向影响,并且研发强度对利用式创新的作用要大于对探索式创新的作用。因为制度差异,国有企业属性会负向调节研发强度与双元技术创新的正向关系。同时企业规模对研发强度与利用式创新正向关系产生正向调节作用,对研发强度与探索式创新正向关系产生负向调节作用。

This paper uses the patent data and financial data of 568 Chinese main board listed companies in 2007 - 2010 to examine the influence of RD intensity on firms＇ ambidextrous innovation. It also checks the effect of institutional logic framework on the interpretation of the relationship between RD intensity and firms＇ ambidextrous innovation. Results of negative binomial regression indicate that RD intensity have positive effects on both exploratory innovation and exploitative innovation. Specially,the findings provide strong support for the premise that RD intensity has a stronger effect on exploitative innovation than on exploratory innovation. Because of institutional differences,state ownership has a negative moderating effect on the positive relationship between RD intensity and firms＇ ambidextrous innovation. Meanwhile,firm size has a positive moderating effect on the relationship between RD intensity and exploitative innovation,but a negative moderating effect on the relationship between RD intensity and exploratory innovation.
