跨国公司在华研发投资的效率及影响因素——基于DEA和SFA模型的实证研究

Efficiency and Affecting Factors of Multinational Corporation R&D Investment in China——Empirical Research Based on DEA & SFA Model

综合运用DEA和SFA模型对剔除环境和随机因素前后的我国29省跨国公司研发投资技术效率进行分析。结果表明,我国各地区跨国公司研发投资效率受到通信设施、工资水平、科技水平、企业规模等因素的影响显著;在同质经营环境和运气的条件下,跨国公司在华研发投资效率表现不容乐观,规模效率和纯技术效率均有待提高;跨国公司研发投资效率存在明显的区域差异,西部最优,东部次之,中部最差。最后根据分析结果提出适当调整各地研发投资规模、提高地区工资和科技水平、引导研发投资从东部向西部流动等对策建议。

The paper analyzes the efficiency of multinational corporation R ＆ D investment in 29 provinces of China with and without environmental variables and statistical factors based on DEA ＆ SFA model. The results demonstrate that： the efficiencies of many regions are affected by environmental variables such as information and communication facilities, wage levels, technological conditions, and enterprise sizes. Rejecting the influence of environmental variables and statistical factors, the average technical efficiencies of multinational corporation R ＆ D investment in China are not optimistic ; scale efficiency and pure technical efficiency need to be improved. The regional analysis shows, there is significant regional difference, the west region is best, the east region is second and the middle is worst. For these, related suggestions are given, such as to improve the wage and technological levels, adjust R ＆ D investment scale, guide R ＆ D investment flow from east to west.
