摘　　要：基于SNA2008核算框架,根据我国R&D活动实际情况,采用永续盘存法对1978—2020年中国省际的R&D资本存量进行了测度;在此基础上,通过双向固定效应模型估算了省际R&D资本产出弹性,并对各省R&D资本对经济增长的贡献度进行了测度分析。结果显示:中国省际R&D资本存量总体上呈快速增长趋势,空间上存在典型的“东多西少”分布特征;时序上省际R&D资本配置失衡状况有所减缓,但空间分布的差异性格局未得到根本转变;各省R&D产出弹性估计值皆处于0.06—0.14正向区间内;省际R&D资本对经济增长的贡献率总体呈现不断增强态势,但省际差异性显著,东、中部省际R&D资本对经济增长的拉动作用普遍强于西部地区。Based on the accounting framework of SNA2008,combined with the actual situation of R&D activities in China,this paper uses the perpetual inventory method to scientifically measure China's provincial R&D capital stock from 1978 to 2019;On this basis,this paper reasonably estimates the output elasticity of R&D capital in China through the Two-way fixed effect model,and effectively measures the contribution of R&D capital to economic growth.The results show that:the R&D capital stock of China's provinces generally presents a rapid growth trend,and there is a typical distribution characteristic of‘more in the east and less in the west";with the passage of time,the imbalance of R&D capital allocation in China has slowed down,but the outstanding spatial distribution differences pattern of China's R&D capital allocation among provinces has not been fundamentally changed;the estimated value of China's R&D output elasticity is in the positive range of 0.06-0.14;the contribution rate of provincial R&D cap-ital to economic growth is generally increasing,but there are significant differences between regions,and the pull effect of R&D capital on economic growth in eastern and central provinces is generally stronger than that in western regions.
