区域融合、对外开放与产业集聚发展

区域融合与对外开放通过提高市场一体化水平、促进产业协调和转移升级等方式推动产业集聚。借助长江经济带108个地级市2005-2015年面板数据，对区域融合与对外开放促进产业集聚的作用展开研究。结果表明：区域融合与对外开放均对长江经济带产业集聚产生了显著推动作用，在政府干预行为的支持下这一作用效果更为显著。二者对长江经济带不同地区产业集聚产生了不同的作用结果：在中、上游地区两者均起到了一定程度的促进作用，而下游地区在区域融合对其起积极作用的同时，对外开放表现出抑制作用。最后提出，各地区应当合理协调产业资源，因地制宜实施开放战略，利用产业政策更好地促进产业集聚。

Regional Integration,Opening to the Outside World and Industrial Agglomeration

Regional integration and opening to the outside world will promote industrial agglomeration through improving the level of market integration, promoting industrial coordination and upgrading. With the panel data of 2005-2015 cities in the 108 cities of the Yangtze River economic belt, the role of regional integration and opening up to promote industrial agglomeration is studied. The results show that both regional integration and opening to the outside world have played a significant role in promoting industrial agglomeration of the Yangtze Economic Belt, and the effect of this role is more significant under the support of government intervention. The two groups have different effects on industrial agglomeration in different regions of the Yangtze River Economic Zone:both in the middle and upper reaches of the Yangtze River have played a certain degree of promotion, while the downstream area plays an active role in the regional integration and shows a inhibition effect on opening to the outside world. Policy implication:all regions should reasonably coordinate industrial resources, implement the opening strategy according to local conditions, and promote industrial agglomeration better with industrial policies.
