摘要随着京津冀协同发展上升为国家战略,三地在资源优化配置、空间格局合理利用、产业转移与承接等方面的协同进程逐步深化,技术市场交易额逐步扩大。进一步探究京津冀协同发展政策对技术市场扩张的影响,为推动区域经济高质量发展提供实证支撑。将京津冀协同发展战略实施对区域产生的政策效应、时间效应和个体效应纳入同一分析框架,利用2010—2021年中国31个省份的面板数据构建双重差分模型,评估政策实施后京津冀与其他地区在技术市场扩张的趋势相较于政策实施前的趋势是否存在差异。结果表明:京津冀协同发展政策对区域技术市场扩张的作用显著,但规模以上工业企业实施的科技项目数量越多、投入的科研力量越大,就越会抑制技术市场扩张效应,部分抵消政策实施对技术市场的扩张效应。对此,从加快建立区域内科技创新协调机制、加快技术市场一体化建设、促使京津冀协同发展政策与区域内科技创新投入同向发力等方面提出对策建议。 With the elevation of the policy for coordinated development of the Beijing-Tianjin-Hebei region to a national strategy,the collaborative process in optimizing resource allocation,rational utilization of spatial patterns,and the transfer and reception of industries among these three regions has gradually deepened,leading to a steady expansion of the technology market transactions.This paper further explores the impact of the policy for coordinated development of the Beijing-Tianjin-Hebei region on the expansion of the technology market,in order to provide empirical support for promoting the high-quality development of regional economy.Integrating the policy effects,time effects,and individual effects of the implementation of Beijing-Tianjin-Hebei coordinated development strategy on the region into the same analysis framework,a difference-in-differences model is constructed by using provincial panel data of 31 provinces in China from 2010 to 2021,to evaluate whether there is a difference in the trend of technology market expansion in Beijing-Tianjin-Hebei compared to other regions before and after the policy implementation.The research results indicate that the policy for coordinated development of the Beijing-Tianjin-Hebei region has a significant effect on the expansion of the regional technology market.However,the greater the number of scientific and technological projects implemented by large-scale industrial enterprises and the larger the input of research efforts,the more the effect of the technology market expansion is inhibited,offsetting some of the expansion effects of the policy on the technology market.Based on these findings,the following countermeasures are proposed:speeding up the establishment of a regional science and technology innovation coordination mechanism,as well as the integration of the technology market,and aligning the Beijing-Tianjin-Hebei coordinated development policy with regional science and technology innovation input.
