“是否研发”与“投入多少”:兼论企业研发投资的两阶段决策
发布时间：2018-10-25 08:15
【摘要】：研发投资是企业提高技术创新能力和市场竞争力的重要途径。与以往研究不同,针对中国企业研发参与度小和投入强度低的现实,本文从企业属性、行业特征和外部冲击三个角度探究了研发投资的决定因素及作用机制,进而利用Heckman两步法建立选择和投资方程,以2007年中国工业企业的微观数据和工业行业的中观数据为样本,就企业研发决策的两面性问题进行了实证检验,发现企业研发行为的选择性偏误确实存在,是否研发与投入多少会受到不同因素的制约,来自所有制分组的回归结果显示,企业性质是影响研发投资的重要因素,国有、外资和私营企业在研发决策机制方面存在巨大差异。
[Abstract]:R & D investment is an important way for enterprises to improve their technological innovation ability and market competitiveness. Different from previous studies, this paper explores the determinants and mechanism of R & D investment from three angles of enterprise attributes, industry characteristics and external shocks, aiming at the reality of low R & D participation and low investment intensity of Chinese enterprises. Then using the Heckman two-step method to establish the selection and investment equation, taking the microcosmic data of Chinese industrial enterprises and the mid-scale data of industrial industry as samples in 2007, this paper makes an empirical test on the two-sided problem of enterprise R & D decision. It is found that the selective bias of R & D behavior of enterprises does exist, whether R & D and how much investment will be restricted by different factors. Regression results from ownership groups show that the nature of enterprises is an important factor affecting R & D investment. There are huge differences between foreign and private enterprises in R & D decision-making mechanism.
