我国外资企业R&D水平的决定因素

On the Determinants of R&D Level of Foreign-Invested Enterprises in China

鼓励外商进行R&D投资以推动技术进步是我国利用FDI的重要目标,但成效与目标相去甚远。FDI企业的R&D水平低,这既与外资企业R&D动机有关,也与我国区位条件有关。利用27个省、市、区2003-2007年的面板数据模型进行经验分析表明:经济发展水平、市场规模、外资规模等与外资企业R&D水平正相关,而R&D人力资本、贸易体制的开放水平等与外资企业R&D水平反相关。R&D人力资本、市场导向、生产的本地化程度回归系数符号为负与现有的研究结论不一致,主要原因可能是知识产权保护水平不高。

To encourage foreign investment in R＆D to promote technological progress is an important goal of China＇s use of FDI, but the results are far from expected. The low level of R＆D in FDI enterprises is directly related with both the motivation of foreign-invested enterprises and the conditions of location in China. By making use of the panel data model of 27 provinces, cities and regions from 2003 to 2007, this paper performs an empirical analysis of this subject. The results show that such elements as economic development level, market size, foreign investment scale, etc. have a positive correlation with the R＆D level of foreign-invested enterprises; while such elements as the R＆D human capital, the opening level of trade system, etc. have a negative correlation with the R＆D level of foreign-invested enterprises. The signs of regression coefficient of R＆D human capital, market orientation, and level of localized production are negative, which is not consistent with the existing research findings, the major reason being lacking of enough protection of intellectual property right.
