As more and more multi- national companies increase their R&D investment in China , the degree of R&D globalization in China has witnessed quicker and quicker growth . However , the degree of R&D globalization in eastern China is remarkably higher than that in western provinces . By evaluating the degree and efficiency of provincial R&D globalization and analyzing how local factors affect the degree of R&D globalization via the impact of efficiency of R&D globalization , this study shows that in the areas with a higher degree of R&D globalization , the technological changing rate tends to be lower and the technological efficiency rate tends to be higher , and vice versa for areas with lower R&D globalization . The efficiency of R&D globalization has a strong positive effect on the degree of R&D globalization;specifically , in the areas which have bigger market volume , more direct foreign investment , more abundant local R&D resources or stronger intellectual property rights protection , technical efficiency exerts a stronger impact;otherwise , the technological changing efficiency plays a more important role . Based on the above analysis , this paper puts forward four pieces of relevant suggestion .
