摘要
本文运用2010-2014年中国上市公司与商务部《境外投资企业(机构)名录》匹配后的数据,基于内生转换回归(ESR)模型和边际处理效应(MTE)的参数估计方法,估计了企业反事实专利数量,在考虑了异质性效应的基础上估计了对外直接投资对中国企业技术创新的影响。结果表明:对外直接投资有助于提高中国企业的技术创新能力;规模大、研发费用高、人力资本投入高以及所得税率低的企业,专利数量相对较高;越倾向于进行对外投资的企业,对外投资提升其专利数量的边际处理效应越高;而那些不具备比较优势的企业如果对外投资,反而可能会降低企业的专利数量;国有企业、综合型对外投资企业以及投资到发达国家(地区)的企业如果选择对外投资,对企业技术创新能力的提升作用更大。
This paper estimates counterfactual number of patents for OFDI and non-OFDI enterprises and the heterogeneous effect of OFDI on China enter- prises' number of patents based on endogenous switching regression (ESR) mod- el and parametric marginal treatment effect (PMTE) method using the matching data of China listed companies and "overseas investment list enterprises (Institu- tions)" published by the Ministry of Commerce during the period 2010-2014. Generally speaking, OFDI helps to improve the technological innovation capabili- ty of Chinese enterprises. Enterprises with large scale, high R&D expenditure, abundant human capital and low tax rate tend to own more patents. The stronger the intention of OFDI, the greater OFDI' s promoting effect on enterprises' pat- ents. However, those enterprises without any comparative advantages may reduce their number of patents if they really go abroad. In addition, the investment of state-owned enterprises, comprehensive foreign investment enterprises and enterpris- es investing in developed countries tends to have greater promotion effect ontech- nological innovation.
