为了揭示区域间科技差距的原因所在,以专业化分工理论为基础,建立了一个动态层级式科技发展模型。结合1997-2007年面板数据,运用shapley值分解方法对中国区域科技差异进行分解。研究结果发现:(1)R&D研究人员数量和市场结构(市场化指数k)对区域科技发展影响较大;(2)区域间的国家R&D经费投入,研究人员数量以及地方政府的科技拨款对形成区域间科技差异的贡献较大;(3)地方政府的科技拨款对区域间科技差异贡献率有上升趋势,而R&D经费的科技差异贡献率却趋于下降。
In order to reveal the reasons for the disparity in science and technology among regions, a dynamic hierarchical technology development model was established based on the specialization of labor division theory. Combining with the panel data from 1997 to 2007, we use the shapley value decomposition method to decompose the regional differences in science and technology in China. The results show that: (1) The number of R & D researchers and the market structure (market index k) have a great impact on the development of science and technology in the region; (2) The investment in R & D, the number of researchers and the funding of science and technology from local governments (3) There is an upward trend in the contribution rate of science and technology among local governments to technological differences among regions, while the contribution rate of scientific and technological differences in R & D expenditure tends to decrease.
