| 摘 要： | 基于中国医药制造业的视角,对政府科技资助与企业RD投入的关系进行实证研究。利用中国医药制造业企业2000—2015年省际面板数据,采用系统广义矩估计法(SYS-GMM)和Hansen提出的"门槛回归模型",测算政府科技资助与企业RD投入之间最优资助区间或强度。结果显示,政府科技资助与企业RD投入之间不仅存在显著促进作用,还存在门槛效应。最优资助强度(政府科技资助与RD投入比)为8.1%,随政府科技资助强度的增大,企业RD投入呈现先增大再变小的趋势,当政府科技资助强度超过19.6%,为显著负相关,总体呈倒"U"型。根据研究结果,提出优化政府资源配置的建议。

Threshold Effect of Government Subsidies on Enterprises |
| |
| Abstract: | In this paper, we use the "threshold regression model" proposed by Hansen to estimate the optimal funding range between government subsidy and R D investment of pharmaceutical enterprises by using the provincial panel data of China"s pharmaceutical manufacturing industry from 2000 to 2015. Firstly, the System-GMM generalized moment estimation method is used to test the effectiveness of government subsidy for R D investment in pharmaceutical enterprises. Then, the nonlinear relationship between them by the threshold effect. Analyzes and puts forward some suggestions on the government subsidy intensity of each province. The results show that there is not only a significant relationship between government subsidy and R D investment in pharmaceutical enterprises, but also the threshold effect. The optimal funding range is within 8.1%, and the optimal funding rate is 8.1%. With the increase of government subsidy intensity, the R D investment of pharmaceutical enterprises is increasing first and then decreasing. When the government subsidy is more than 19.6% Significant negative correlation, the overall presentation of inverted "U".. |
