摘 要：作为地区经济增长极和推动高质量发展的主要载体，开发区近年来备受学界关注。文章基于长三角开发区合作共建的背景，采用空间计量模型研究了长三角地区具有共建关系的开发区经济绩效增长特征，以及共建关系对经济绩效增长的影响机制。结果表明：第一，开发区共建有利于实现经济共赢。第二，在共建开发区中，高发展水平开发区之间的学习效应较强，经济增长的同步特征明显；低发展水平开发区具有持续的“向上学习”特征，有利于强化经济增长的同步效应。第三，基于共建关系形成的招商合作有利于双方经济增长，而税收合作与土地合作对共建双方经济增长效应具有较强的不确定性。上述研究对于各大城市群从开发区合作共建角度开展区域一体化建设，进而实现共同富裕具有重要意义。

Key words：co-construction of development zones；economic effect；the Yangtze River Delta

Abstract：As the growth pole of the regional economy and the main carrier of promoting high-quality development，the development zone has received much attention in recent years. Based on the background of cooperative construction of development zones in Yangtze River Delta，this paper studies the growth characteristics and influence mechanism of economic performance of development zones with the co-construction relationship. The results show that：Firstly，co-construction relationship is conducive to the development zones' economic win-win. Secondly，in the co-construction development zones，the learning effect between the developed development zones is strong，and the synchronization of economic growth is obvious. And the underdeveloped zones are characterized by continuous "upward learning"，which is conducive to strengthening the synchronous effect of economic growth. Last but not least，investment cooperation based on the co-construction relationship is conducive to the economic growth of both sides. However，the impact of tax cooperation and land sharing on economic growth is not stable. The research is of great significance for urban agglomerations to carry out regional integration construction from the perspective of cooperation and co-construction of development zones and achieve common prosperity.

一、引 言

以城市群构建区域协调新发展格局为建立优势互补，高质量一体化发展的区域经济布局提供了具体路径。自党的十九大对实施区域協调发展战略作出重要部署之后，党的二十大再次强调了深入实施区域协调发展战略、区域重大战略，充分体现了中央对实施区域协调发展战略的高度重视。长三角地区作为中国经济发展的重要增长极，在1982年成立上海经济区后就开始了区域一体化发展的探索道路。其中，跨地区的开发区合作便是推动长三角区域经济一体化发展的路径之一。……
