油气资源型城市生态工业园产业耦合共生网络生态效率评价

Eco efficiency evaluation of industrial coupling symbiosis network in eco industrial parks of oil-gas resources cities

摘要:

生态工业园是一个复杂的系统，它由多种企业和嵌入关系组成，园内各生态企业间构成“产业生态链网”，链网中的企业相互促进，互惠互利，构成了产业耦合共生网络系统。为分析生态工业园产业耦合共生网络的发展水平，应用灰关联模型对油气资源型城市生态工业园产业耦合共生网络生态效率进行评价，结果表明，通过经济、环境、物质减量循环和网络结构关联度分析能反映产业耦合共生网络生态效率的总体水平及网络稳定性状态，进一步验证了评价指标体系和评价模型的可行性和可操作性。

Abstract:

The eco industrial park is a complex system. It is composed of many enterprises and embedded relations. The ecological enterprises in the garden constitute the "industrial ecological chain network". The enterprises in the chain network promote and mutually benefit each other, and constitute the industrial coupling symbiotic network system. In order to analyze the development level of the industrial coupling symbiotic network in the eco industrial park, the grey relational model is used to evaluate the ecological efficiency of the industrial coupling symbiotic network of the oil and gas resource-based urban eco industrial park. The results show that the industry coupling symbiotic network can be reflected by the economic, environmental, material reduction cycle and the network structure association degree analysis. The overall level of ecological efficiency and the state of network stability further verify the feasibility and operability of the evaluation index system and evaluation model.
