国家创新驱动发展战略的实施需要充分掌握中国技术创新的投入水平,而R&D资本存量是其重要组成部分。本文根据R&D活动的特点,重新设定了滞后期、折旧率、R&D支出价格指数和基期资本存量等参数,再采用永续盘存法对1998-2012年间中国大陆31个省市区的区域R&D资本存量进行重新估算。同时,本文还采用Theil指数测算了中国R&D资本存量的地区差距。结果表明:(1)绝大部分地区的R&D资本存量均呈增长趋势,但在2001年后其增长速度逐步放缓;(2)R&D资本存量差距由以地带内的差距为主向以地带间的差距为主转变;(3)总体差距和地带间差距的演变轨迹类似于“V”型,而地带内部差距不断缩小并趋于平稳。
The implementation of the national innovation-driven development strategy needs to fully grasp the input level of China’s technological innovation, and the R & D capital stock is an important part of it. Based on the characteristics of R & D activities, the paper researches parameters such as lag period, depreciation rate, R & D expenditure price index and base period capital stock, and then uses perpetual inventory method to analyze the regional R & D capital of 31 provinces and municipalities in mainland China from 1998 to 2012 The stock is re-estimated. At the same time, this paper also uses the Theil index to measure the regional disparity of R & D capital stock in China. The results show that: (1) The R & D capital stock shows an increasing trend in most regions, but its growth rate slows down gradually after 2001; (2) The R & D capital stock gap is dominated by the intra- (3) The evolutionary gap between the overall and inter-regional differences is similar to that of the “V” type, while the intra-regional gap is gradually narrowing and tends to be stable.
