摘要 本文利用匹配后的微观企业数据,通过Probit模型和PPML模型实证检验了双向投资通过双向技术溢出效应对中国企业创新决策和创新绩效的影响。研究发现:制造业双向投资的协调发展,总体上有利于我国制造业企业做出创新决策,且从创新产出和创新投入视角均得到较为稳健的结果。对于不同行业,双向投资的这种影响呈现倒U型,即中等技术行业的影响相对较大,高技术、低技术行业的影响则相对较小;且东部地区、外资企业同样表现出显著的促进作用。从创新决策来看,双向投资的增长通过技术溢出效应有利于提升企业的创新绩效,且对中等技术企业、东部和西部地区企业、外资企业的表现更为明显,国有企业双向投资的协调效应不利于企业创新绩效的提升,私营企业的影响则并不显著。

Abstract:Based on the matched micro-data of the firms,this paper makes an empirical test to explore the influence of bidirectional investment,in the means of bidirectional technology spillovers effect,on the innovative decisions-making and innovative performance among the firms in China by adopting the Probit Model and PPML Model.The study finds out that the coordinated development of bidirectional investment in the manufacturing industry is generally beneficial for China's manufacturing companies to make innovative decisions.In addition,robust results are gained from the perspective of innovation output and innovation investment.This impact of bidirectional investment,which varies from different industries,presents an inverse U-shape curve,namely,it has relatively greater effect on the medium-technology industries,while smaller influence on both high-tech and low-tech industries.What's more,it remarkably contributes to the development of the firms in the eastern region and the foreign-owned firms.From the perspective of innovative decision-makings,the increase of bidirectional investment,through technology spillover effect,benefits the innovative performance in a company,and it shows evident advantage on medium-technology industries,the industries in the eastern and western regions as well as the foreign-owned firms.However,bidirectional investment in state-owned firms shows detrimental effect on the development of innovative performance and unremarkable effect on private firms.
