Research on the Economic Synergistic Degree Between Renewable Resources Industry and Equipment Manufacturing Industry in Industrial City
研究了天津可再生资源产业与装备制造业在2003-2009年间的协同度，发现两者协同指数上升，模式从传统合作转向可再生资源产业跟随型。
For the shorter trend of product life cycles for equipment manufacturing industry,the order parameter indicators of economic system was selected in order to analyze the ordering degree between renewable resources industry and equipment manufacturing industry.The entropy method was applied to evaluate the order parameter and calculate cooperative modulus.Capacity coupling coefficient model was treated as the basis for constructing the synergistic degree model,which showed the interaction between systems.According to the synergistic degree model,the standard of distinguishing level was set.As a research object,synergistic status and development trend of the renewable resources industry and equipment manufacturing industry in Tianjin was researched.The results showed that: in the period of 2003—2009,the index of cooperative and synergistic degree between the two systems was increased and in the overall ascending trend.The synergistic model is transforming from traditional cooperative model to renewable resources industry followed model.Finally,suggestions were proposed to promote synergistic degree between the two systems.In order to provide quantitative decision of coordinate the development between renewable resources industry and equipment manufacturing industry with support.
