Research On The Network Structure And Its Effect Of Eco-Industrial Park

Under the growing pressure from resources and the environment, the Eco-Industrial Park (EIP), as a form of circulation economy, has been widely applied in practice home and abroad. This new producing pattern has been pinned on great expectations from the government and the society. Many EIPs indeed harvested economical, social and environmental benefits; some others, however, met various difficulties, which might be cruel enough to lead them to disintegration. Present relative researches usually concentrate on the concept of EIP, the environmental benefits it may bring about, the design of the material and energy flow, or a brief introduction of single or several EIPs, while benefits and risks in practice have seldom been studied systematically by scholars. Therefore, this paper, from a new angle, applies the techniques of society network analysis (SNA) and systematic analysis to analyze the special network structure of EIP, and the positive and negative effects it may bring about. It is to solve some problems met in the practical use of EIP, thus featured with significance both in theory and in practice.The goal of EIP and the basic components of the network are analyzed firstly in this paper with a CSP model on network level of EIP presented afterwards, based on which, variables, including strong ties, network density and network centricity that are commonly used in SNA are involved to describe the characteristics and analyze the effects of its network structure. Apart from different small cases inserted, this paper made a key demonstration analysis on Guigang Eco-Industrial Park. Proposals for the network management of EIP were presented based on the analysis above.This paper mainly concludes as follows: Common EIPs are featured with obvious strong ties, big network density, and high network centricity. These characteristics assure the EIP considerable benefits, such as higher level of resource rate and stronger ability of resource collocation and integration, but, on the other hand, also bring some adverse effects, including network costs increase, additional network-income net loss, innovation capability restriction, periodic risks suffering and path dependence and lock. Policies of network management should be adjusted to different phases of the three dimensionalities (strong ties, network density and network centricity) in the lifecycle of the EIP.
