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 %K export trade %K R & D investment %K maximum likelihood estimation %K propensity score matching method %K learning by exporting %U http://www.zndxsk.com.cn/Article_View_temp.asp?type=3145&ID=3145
