Abstract

The opening of high-speed rail (HSR) and the operation of enclave parks (EP) are both important cross-regional economic activities that play a pivotal role in promoting regional economic development. This study modifies the previous single-dimension research paradigm of the HSR effects and EP effects, focusing on the synergistic relationship between HSR and EP in the process of urban economic development. We design a staggered difference-in-differences (DID) model based on the realistic background of the synchronized development of HSR and EP in the Yangtze River Delta region to test the joint impact of HSR and EP on the urban economy, and its heterogeneous performance and mechanisms. The results indicate that the joint impact of HSR and EP on the urban economy is superior to their individual impacts, confirming the synergistic effect of the HSR and EP. In addition, the joint impact of HSR and EP on the urban economy is heterogeneous. The joint economic effects of the HSR and EP are stronger in the fly-out cities of enclave parks. Core and large-scale cities benefit more from the synergistic economic effects of HSR and EP. In terms of the sequence of intervention, the operation of the EP after the opening of HSR can better accelerate economic growth. Finally, we demonstrate that HSR and EP can promote economic development synergistically by alleviating urban resource misallocation and that market development has an important moderating effect on the synergistic effect of HSR and EP.

评估长江三角洲地区高铁和飞地园区的共同经济效应

高铁（HSR）的开通和飞地园区（EP）的运营都是重要的跨区域经济活动，在促进区域经济发展方面发挥着举足轻重的作用。本研究改变了以往高铁效应和飞地园区效应的单一维度研究范式，重点研究高铁和飞地园区在城市经济发展过程中的协同关系。我们基于长三角地区高铁与环保同步发展的现实背景，设计了交错差分（DID）模型，检验高铁与环保对城市经济的共同影响及其异质性表现和机制。结果表明，高铁和环保对城市经济的共同影响优于各自的影响，证实了高铁和环保的协同效应。此外，高铁和 EP 对城市经济的共同影响具有异质性。在飞地园区的飞出城市中，高铁和延长线的联合经济效应更强。核心城市和大型城市则更多地受益于高铁和环保的协同经济效应。从干预顺序上看，在高铁开通后再运行飞地园区更能加快经济增长。最后，我们证明了高铁和环城高速可以通过缓解城市资源错配协同促进经济发展，而市场发展对高铁和环城高速的协同效应具有重要的调节作用。

期刊介绍： Habitat International is dedicated to the study of urban and rural human settlements: their planning, design, production and management. Its main focus is on urbanisation in its broadest sense in the developing world. However, increasingly the interrelationships and linkages between cities and towns in the developing and developed worlds are becoming apparent and solutions to the problems that result are urgently required. The economic, social, technological and political systems of the world are intertwined and changes in one region almost always affect other regions.
