urban spatial structure and Coordinated development of regional economyUrban and region is an interrelated organic whole. With the links of region and urban space continue to strengthen, Urban spatial structure is piaying a increasingly important role in the Coordinated development of regional economy, and therefore strengthen research of urban spatial structure and Coordinated development of regional economy is necessary. 1.what is urban spatial structure? Space is the basic form of urban existence. History shows that urban development is the result of the interaction of natural and human factors, which is a relatively complex process. Urban spatial structure is mainly from the perspective of space to explore the organization of urban form. About connotation of urban spatial structure, there are two main different views. One is that the spatial structure of urban spatial structure mainly refers to the inner city. It is a combination of different functional spaces inside city. Second is a hierarchy of urban spatial structure, including the urban internal spatial structure and urban outer space structure . The urban internal spatial structure mainly discuss the Angle of the city itself , refers to the uses of the city inside land and urban functional structure and combination; Urban outer space structure regard the city as a whole, including the city itself and its town and a central city and its surrounding cities of radiation area , commonly referred to as the urbanized regions (city group) is the most typical urban outer space structure and the most representative2.what is Coordinated development of regional economy？ Unbalanced regional economic development is a historical problem, is also a realistic problem. Promote regional harmonious development, is the strategic task of reform and opening-up and socialist modernization construction.It is also the inevitable requirement to construct well-off society and a socialist harmonious society . Therefore, how to understand the scientific connotation of coordinated development of regional economy, has important theory value and practical significance. the following are main views in china now: 1) Development expounds: regional economic coordinated development is in the process of unbalanced regional economic development, which pursuit to regional relative balance, with the ultimate goal is to achieve regional harmony. 2)Process state theory: regional economic coordinated development is under the condition of the regional internal opening to the outside world, between different regions of interdependence, mutual adaptation, mutual promotion and common development of the state and process, which form a decision in this state and in the process of the operation mechanism of inner stability. 3) development theory: regional economy coordination development is point to the process of the development of the national economy, which mainly from the Angle of the efficiency and the balanced consideration of both different Yu Junheng development, also is different from the unbalanced development of a regional economic development pattern. It has four distinctive features: first, emphasis on efficiency and fairness, give attention to two or morethings ，secondly focus on developing, the third emphasizes the complementary advantages, the fourth emphasizes the common development. 4) the theory of development strategy: Regional harmonious development is in the process of national economic development, both to maintain efficient growth in regional economy as a whole, and promote the regional economic development. The regional development gap between stability within the scope of the reasonable moderate convergence gradually achieve the regional coordination interaction. Regional economic coordinated development is a process, or a state? Is a pattern, or a strategy? I think it Can be used as a kind of development model, and can be used as a development strategy. We must from the implementation of the scientific outlook on development and building a harmonious socialist society of the strategic place to promote coordinated development of regional economy in a more important position. 3.the relations of the urban spatial structure and the coordinated development of regional economic . Cities and regions is a mutual connection, interdependence, mutual promotion of the overall, both the premise and condition each other .city is the regional growth pole, is the area City is the regional growth pole, is the core of the region, is the carrier of city and region, support and diffusion hinterland, both inseparable. The 21st century is the century of urbanization, urbanization has become the main carrier and the impetus of Chinas regional economic development, multi-center urban space layout has become the strategic choice for the development of Chinese cities. Urban spatial structure in the position and role of the coordinated deve
