Time Trend Effects Analysis.

Regional integration is a key strategy for enhancing competitiveness and promoting innovation, and regional education integration has become an important part of regional integration. At the same time, university-industry-research (UIR) collaborative innovation is also a key link in building a national innovation system. This study empirically analyzes the impact of China’s Yangtze River Delta regional education integration policy on UIR innovation cooperation by using a difference in difference model. The results show that the regional education integration policy significantly promotes UIR innovation cooperation, especially in Zhejiang and Jiangsu, which have a stronger economic base and richer educational resources. In addition, the policy has an extraordinarily prominent role in promoting invention patents with higher innovation intensity. The mechanism analysis finds that human capital, economic capital, government support and social stability play an important mediating role. Finally, policy recommendations are made based on the empirical results.区域一体化是提升竞争力与推动创新的核心战略，而区域教育一体化业已成为区域一体化的重要组成部分。与此同时，产学研（university-industry-research, UIR）协同创新亦是构建国家创新体系的关键环节。本研究采用双重差分（difference in difference）模型，实证分析中国长江三角洲区域教育一体化政策对产学研协同创新合作的影响效应。研究结果表明，该区域教育一体化政策可显著促进产学研协同创新合作，尤其在经济基础扎实、教育资源更为丰裕的浙江与江苏两省，政策实施效果更为突出。此外，该政策对创新强度更高的发明专利的促进作用尤为显著。机制分析发现，人力资本、经济资本、政府支持与社会稳定均发挥了重要的中介传导作用。最后，本研究基于实证分析结果提出了相应的政策建议。
