In this paper, the method of generalized moments of data and systems for 101 counties in Jiangsu and Zhejiang Provinces is used to analyze the impact of industrial agglomeration and industrial structure upgrading on county economic growth. The real diagnosis result indicated that, the industry gathers with the industrial structure promotes has the forward function to the county territory economic growth rate, in the sample time that had not discovered the industry gathers to the economical growth existence non-linearity in？ uence. On the other hand, the industrial structure promotes to the county territory economy long-term growth power is stronger, later period should break through the present stage in the manufacturing industry mature county territory through the industrial structure promotion strategy the industry to glide down.

The resource-based city can divides according to the Israeli resource type and development phase two big standards. The resource-based city economic transformation strategy first should from the macroscopic level, seek for the regional economic development the new superiority, next should act according to the new regional development favorable condition that establishes the pattern of industrial transformation from the microscopic level.

Integrated development of industrial cooperation is the core content in the Bohai economic *** structure convergence of Bohai economic rim mainly exist in macro three industries while it rarely exist in the manufacturing industry and other internal meso level. Learning from changing tendency, industrial structure convergence in the five provinces and municipality in the Bohai Economic Rim tend to be increasingly intense. For integration of industry cooperation development in Bohai Economic Rim, it is faced with massive separation, industrial development convergence and is restricted by institutional and ideological barriers. As strategic choice based on interest tending, integration of industry cooperation development in Bohai Economic Rim should be further integrated on development concept of industrial transformation to promote institutional system of the integration of industrial development and optimize the industrial layout and division system of Bohai economic rim.
