Abstract
Under the guidance of five development concepts, we should grasp regional overall economic, innovation, and traffic associated structure macroscopically, and analyze cities' status and role within the region when planning the regional green design. Through systematically considering regional overall structure, relationship between subjects and individual differences without prejudice to the ecological environment, it can play the greatest role of traffic led, city led, and market led, which can achieve regional green development. We build the traffic interaction network model, economic correlation network model, and innovation-driven network model to analyze network structures, identify key nodes and provide methodological guidance for regional green development plan. We bring Beijing-Tianjin-Hebei Urban Agglomeration for the case study and draw the following conclusions. The traffic interaction network is closer than the economic correlation network and the innovation-driven network, and the economic correlation network is closer than the innovation-driven network. The three networks all have a high degree of centralization, which means there is a great difference among cities. Beijing, Tianjin, Shijiazhuang develop relatively well, however, Chengde, Hengshui and Zhangjiakou relatively fall behind. Dezhou has a foundation to promote transportation integration and lacks the economic momentum and innovation driven. Chengde should increase the degree of innovation and communication to build connection with other cities.
Highlights
Green development and sustainable development is the trend of times in the world
The essence of green development is to reduce the excessive consumption of resources, strengthen environmental protection and ecological management, and pursue the sustainable development of economy, society and ecology
Based on the social network analysis theory, the regional green development should focus on the analysis of the location and role of the cities in the region, as well as the relationship between the subject and individual differences, under the premise of not break the ecological environment
Summary
Green development and sustainable development is the trend of times in the world. The essence of green development is to reduce the excessive consumption of resources, strengthen environmental protection and ecological management, and pursue the sustainable development of economy, society and ecology. The social network analysis is a new perspective on the social relationship of many questions about interdisciplinary research on a different structure level. 1.3 Social network analysis and regional green development Social network analysis has developed rapidly in recent twenty years It has become a mature theory and method, which has been widely used in sociology, political science, anthropology, psychology[9], organizational management, mass communication, policy research and engineering science[10]. Based on the social network analysis theory, the regional green development should focus on the analysis of the location and role of the cities in the region, as well as the relationship between the subject and individual differences, under the premise of not break the ecological environment. By using the social network model and the center degree, degree distribution, average path length, clustering coefficient, betweenness and other social network indicators, we can set reasonable standard value of regional industrial density, connectivity
