摘　　要：一国产业升级和经济增长的关键因素在于创新,而研发活动是创新的重要来源。本文利用面板数据模型,结合主成分分析法,研究了中国贸易投资一体化对研发投入的影响。本文发现,贸易一体化对研发投入没有影响,投资一体化对研发投入有显著的负作用,基于生产、贸易和投资的全球化对研发投入有抑制作用。此外,本文还发现中国目前的要素密集度和企业规模水平不利于研发投入的增加。The most important factor of industrial upgrade and economic growth is innovation,and R&D activities are the important origin of innovation.This paper explores the effect of integration of trade and investment on the R&D investments by panel data model and principal components analysis.It finds that the integration of trade has not a significant impact on R&D investments,the integration of investment has a negative impact on R&D investments,and the globalization of production,trade and investment has restraint R&D investments.Furthermore,the paper finds that factor intensity and firm scale have a negative impact on R&D investments.
