摘要:基于民营企业调查数据，采用最大似然估计和倾向得分匹配考察了出口贸易对民营企业研发投入的影响。发现出口贸易对企业研发投入存在显著的“出口中学”效应，并随着出口规模的扩大，这一效应不断提升，但这一效应仍存在较大提升空间；高新技术行业、规模较大的企业出口学习效应较显著，而市场化程度高的地区反而相对较低。） |

| Abstract: Based on data of the private enterprises in china, this essay, by adopting the maximum likelihood estimate and propensity score matching method, analyzes the impact of export trade on private R & D investment. The results show that learning by exporting increased R & D investment, and with the expansion of export trade, the effect has increased, yet with a remarkable margin for improvement. High-tech industry and large-scale export enterprises have the most prominent learning effects, while such effects are less significant in the area with higher market-based degree. |
