海峡西岸城市群协调发展规划对区域经济增长的影响

利用双重差分模型，探究海峡西岸城市群的建立对区域经济增长的影响。结果表明，海峡西岸城市群的设立对区域经济增长有显著正向作用，在加入众多控制变量后政策效应依然显著为正，基于PSM-DID估计方法的检验也得到了基本一致的结论。据此，建议加强地方政府的支持与引导，强化中心城市在海峡西岸城市群建设中的核心引领作用，同时因地施策，促进区域内产业分工与合作，进而促进区域经济增长。

The Coordinated Development Plan of Urban Agglomeration on the West Coast of the Taiwan Strait and Its Influence on Regional Economic Growth

This paper uses difference-in-differences model to explore the influence of the establishment of urban agglomeration on regional economic growth on the west coast of the Taiwan Strait. The results show that the establishment of urban agglomeration on the west coast of the Taiwan Strait has a significant positive effect on the growth of the regional economy, and the effectiveness is still significantly positive after many control variables are added. The test based on the PSM-DID also gets basically the same conclusion. Therefore, it is suggested to strengthen the support and guidance of the local government, reinforce the core leading role of the central city in the construction of the urban agglomeration on the west coast of the Taiwan Strait, and implement policies according to the local conditions to promote the industrial division and cooperation in the region, so as to further promote the growth of the regional economy.
