中文摘要：

以长江经济带127个地级以上城市为研究对象,分析了改革开放以来长江经济带的市域经济空间发展格局及其驱动因素。结果显示：长江经济带经济发展的绝对差异持续扩大,但差距增长的速度逐渐减慢;长江经济带经济空间集聚呈先增强后减弱的趋势;长江经济带人均GDP相对增长率的热点区分布总体较为稳定,但西部地区存在较为明显的阶段性特征;地理区位、历史、经济发展、人文等因素是形成长江经济带经济增长格局演进特点的驱动因子。基于此,提出推动长江经济带缩小区域经济发展差异,实现经济增长速度和质量双重提高的3点对策：（1）坚持绿色发展之路,引导产业结构调整;（2）创新区域合作机制,促进生产要素合理流动;（3）加快大城市群建设,加强综合交通建设。

英文摘要：

With 127 cities along the Yangtze River economic belt as the research object,this paper analyzes the development pattern of the economic belt and the driving factors since reform and opening up.It is found that the absolute disparity of the economic development of the Yangtze River economic belt has expanded continuously,but the disparity growth has gradually slowed down.In addition,the economic spatial agglomeration of the Yangtze River economic belt has shown a tendency of strengthening at first and then weakening.The hot spot distribution of per capita GDP relative growth rate along the Yangtze River economic belt is generally stable,but the western region shows relatively salient stage features.It is also found that the driving factors for the formation of the economic growth pattern of the Yangtze River economic belt are geographical location,history,economic development,humanities.Based on the above findings,this paper raises three strategies to narraow the regional economic development differences of the Yangtze River economic belt and acheive the dual increase of economic growth and quality.First,highlight green development and offter guidance to industrial structure adjustment.Second,innovate regional cooperation mechanism and promote the rational flow of production factors.Third,accelerate the construction of large urban cluster and strengthen the comprehensive traffic construction.
