中文摘要：

从经济基础、经济增长和经济结构等方面构建了地区经济发展水平的综合评价指标体系,并采用因子分析法和ESDA方法,从地级行政区尺度对东北振兴战略实施以来的经济发展水平、空间格局及演化规律进行研究。研究发现：过去十多年来,东北地区整体经济发展水平取得了一定的成就,但内部发展差异呈扩大趋势,黑龙江省北部成为东北经济发展最薄弱的地区;在空间上,东北经济发展呈现出集聚性,并主要表现为核心-边缘、轴带集聚发展以及沿海-沿边等空间分异模式。

英文摘要：

In recent years,the economic development of Northeast China has come to the new normal state,the overall economic development has grown downward,and the phenomenon has become the focus concerned by researchers and the society.However,the development gap between cities is gradually expanding,and it has become a main barrier for Northeast China to achieve all-round well-off society.As such,this article builds a comprehensive evaluation index system for economic development level by three terms of economic base,economic growth and economic structure.Then the paper comprehensively studies the economic development,spatial differentiation and its evolution of Northeast China over its revitalized 10 years through factor analysis method and ESDA.The results are as follows：1） Over the past 10 years,the economic development of Northeast China has obtained a certain degree of improvement.But the overall economic development level of Northeast China rises first and then decreases.2） The economic development of Northeast China is spatially clustered,and the trend is strengthened over time.Meanwhile,the differences of cities on Northeast China are expanding.The northern area of Heilongjiang province is the weakest area of economic development level in Northeast China.3） The economic development level of the cities whichareold industrial bases has been promoted at a certain degree,while that of the resource-based cities has been declined.The differences of economic development of the resource-based cities are more significant.Among the resource-based cities,the economic development level of the recessionary cities decline seriously,such as Yichun,Hegang,Shuangyashan,Qitaihe and Daxing＇anling.At the same time,these cities only belong to the resource-based cities.4） In terms of the economic development of Northeast China,it shows three kinds of patterns：the core-periphery mode with the core of four megacities,the agglomeration development pattern with the growth axis from Harbin to Dalian,and the mode with the econo
