Study On The Formation And Optimization Of Region Ecology Industry Chains

Enterprises On the ecological industrial chain achieve the coordinated development of economic and environmental benefits through the exchange of energy and byproduct between each other, the stair utilization of waste and waste-water, and the sharing of infrastructure. The construction of the ecological industrial chain is the foundation of regional eco-industrial development, plays an important role in the harmony and coordinated development of society, economic and environment.Starting with selecting the regional ecological leading industries, this paper explores and researches on the formation mechanism of the regional ecological industrial chain (network), the optimization of the ecological industrial chain, the optimal matching funds in the construction of ecological industrial chain, and other issues. With the actual situation of Shanxi, this paper also research on the Shanxi ecological industrial development mode, leading industry choice and other important issues in the construction of the industrial chain which provide theoretical support and practice guidance to the construction of Shanxi ecological industrial chain, the development of recycling economy, and take the road of the development of green.The innovation research of this article manifests mainly in the following five aspects:(1)On the basis of analyzing the present development of Shanxi energy economic and the series major problem facing by Shanxi province, this paper first proposed a forward-looking, environment-friendly "eco-industrial development model" for the sustainable development of Shanxi Province:The ecological industries Park models and the model of industry chain closure. System dynamics simulation shows that: compared ecological industries to traditional industries development model, the economic and environmental efficiency of earlier are markedly improved.(2)Taking into account the various participants in the game in the case of information loss, the paper introduced the ideological of grey system, proposed the related concept of repeated incomplete information dynamic Grey Game, established a duplicated incomplete information Grey Game dynamic model. On this basis, considering the multi-stage dynamic construction process, take every decision of the business and government as a game process, take the effectiveness function of the government and the enterprises as decision-making variables, and establish a repeated uncompleted information dynamic Gray Game of regional eco-industrial chain to study the formation of the ecological industrial chain.The results show that, there are two basic mechanism of ecological industrial chain: government-oriented and market-oriented. In the condition that market mechanism has not yet fully matures, the construction of the regional ecological industrial chain is more appropriate to use government-led or government and the market more gorgeous model; in the areas of market mechanism more develops, the construction of the regional ecological industrial chain is more appropriate to use market-led approach. (3)This paper presents grey dynamic planning and related concepts, establishes a grey dynamic programming model, and uses standard interval grey number to achieve the optimal solution algorithm of the model, proposes the first and second optimal grey strategy; take classic dynamic programming model extend to the field of uncertainty information. Based on dynamic multi-stage Construction process of the ecological industrial chain, take every building process as a decision-making stage, eco-industry earnings as a decision-making variables, establish the grey dynamic programming model of ecological industrial chain to study the optimization problem of ecological industrial chain, and through empirical research shows the model's feasibility.(4)Based on endogenous economic theory, this paper establishes the output function of the ecological industrial chain Construction and the matching funds optimization model of the ecological industrial chain construction. This paper researches on when bound by relevant available resources, invest funds and institutional constraints, the Government how to rational allocate their ecological industrial chain Construction financial resources and achieve the ecological industrial chain Construction of the greatest benefits. This paper also discusses the profit and loss balance analysis under the condition of multi-element Cobb- Douglas production function, designs the government's profit and loss balance of least investment in the condition of constant scale returns, increasing scale returns, decreasing scale returns and such different types, looks for the Government's effective ways to reduce costs, enhance competitiveness. The results show that: the government matching funds is character by optimality and the effectiveness, when the growth of the government funds is greater than 1, the Government will increase its construction input of ecological industrial chain, or not to increase the inputs.(5)Take Shanxi Province as a major energy research background, in view of a series important issues in the construction of its ecological industrial chain, this paper proposes the corresponding measures and policy recommendations: actively promote "two changes", play their comparative advantages, and create ecological characteristics industrial chain; upgrade support capacity for green industry technology, establish the industry system of eco-industrial; establish property rights system of environmental resources, perfect the eco-market incentive mechanism of industry development; establish and improve the law enforcement system, and strengthen government policy-oriented functions.
