政府R&D资助对高技术产业创新效率的影响—

摘要利用中国2009—2016年高技术产业的省级面板数据,构建SFA模型测度高技术产业的创新效率,先从最优R&D资助规模视角研究了政府R&D资助对高技术产业创新效率的非线性影响以及企业规模对最优R&D资助强度的影响,然后对高技术产业的最优R&D资助强度特征及区间分布进行分析,最后测度了偏离最优R&D资助强度带来的效率损失。研究表明:政府R&D资助对高技术产业创新效率的影响表现为倒“U”形关系,最优R&D资助强度随企业规模变大而提高;现阶段政府R&D资助主要表现为“挤入效应”;东部地区R&D资助强度与最优R&D资助强度差距最大,中部次之,西部最小;全国高技术产业的创新效率损失具有上升的趋势,且效率损失在东部地区最大,中、西部地区较小。

关键词：政府R&D资助最优规模高技术产业创新效率

Abstract： Based on the provincial panel data of China’s high-tech industry from 2009 to 2016, this paper constructs a stochastic frontier approach model (SFA) to measure the innovation efficiency of high-tech industry. From the perspective of optimal R&D funding scale, this paper studies the non-linear impact of government R&D funding on innovation efficiency of high-tech industry and the impact of enterprise size on optimal R&D funding intensity. Then, the characteristics and interval distribution of the optimal R&D funding intensity in high-tech industry are analyzed. Finally, the efficiency losses caused by deviation from the optimal R&D funding intensity are measured. It is found that the impact of government R&D funding on innovation efficiency of high-tech industry can be illustrated as an inverted “U” curve, and the scale of enterprises will improve the optimal R&D funding intensity. At present, government R&D funding brings more “crowding-in effect”. The gap between R&D funding intensity and optimal R&D funding intensity in the eastern region is the largest, followed by the central region and the western region. The loss of innovation efficiency of the national high-tech industry has an upward trend, and there is a largest efficiency loss in the eastern region and the middle and western regions are relatively small.
