The Construction of Low-carbon City Based on Industry Influence and Space Reconstruction

Industrial restructuring and spatial planning are two important factors of low carbon city construction. through the two perspectives of industry influence and space reconstruction,this paper analyzes the idea of low-carbon urban construction in Tianjin based on the meaning of low-carbon city and the construction practice low-carbon city. The main conclusions are as follows. This paper constructs industrial influence coefficient and industrial carbon emission influence coefficient,where most of the industrial influence coefficient volatile near 1,and the industry influence coefficients in Tianjin Eight Competitive Industries including petrochemical industry,equipment manufacturing,electronic information,aerospace and other are greater than 1. The result indicates the balanced development of the industry in Tianjin,and Tianjin Eight Competitive Industries are the engine of social and economic development.Meanwhile,industrial influence coefficient of heavy industries for example,petroleum processing and coking industry,chemical industry is relatively high,which indicates that the carbon emissions of these industry sectors are high and the policy maker should pay more attention on the industries in order to achieve the targets of carbon reduction. There is a significant difference between industrial influence coefficient and industrial carbon emission influence coefficient in various industries,which indicates that Tianjin's leading engine industry is not necessarily accompanied by high carbon emissions. Based on industry influence coefficient,this paper divides the industry sectors in Tianjin into four groups,which are high industrial influence- low carbon emissions industry groups; high industrial influence-high carbon emissions industry groups,low industrial influence- low carbon emissions industry groups,low industrial influence-high carbon emissions industry groups. The group dividing is help to select industries sectors in Tianjin industry development planning and industrial layout. The regional joint development and industrial docking collaboration are important factors to consider in optimizing the layout of the functional areas,so the government of Tianjin should actively improve the mechanisms of regional coordination development,and strive to achieve the Beijing-Tianjin Hebei Metropolitan integrated development. The optimization of industrial function zone layout,the optimization of living function zone layout and the construction of intelligent city are major aspects in reconstruction of Tianjin low-carbon city,the paper gives out recommendations on construction of Tianjin low carbon city from these three aspects.
