Logistic-based network stability study of industrial coupling symbiosis applied to oil-gas-based eco-industrial parks

Abstract

The paper takes the industrial coupling symbiosis network (ICSN) of oil and gas resource-based urban eco-industrial parks (EIPs) as the research object. The purpose is to judge the stability of a symbiotic, one-way relying and two-way symbiosis model applied to oil and gas resource-based cities through constructing a logistic growth symbiotic network model. Through identifying and analyzing the stability model, the research concludes the stability conditions. The analytic results are as follows: In the symmetric ICSN system, it is important to maintain equal status and balanced benefit distribution among the coupled symbiotic enterprises. In the one-way-based ICSN system, the core enterprise significantly promotes the improvement of ecological efficiency the satellite enterprise while the satellite enterprise less effectively promotes the improvement of ecological efficiency of the core enterprise. In the two-way ICSN system, the core enterprise and the satellite enterprise are easily affected by the symbiotic enterprises within the network, and the stability is extremely poor. These conditions and analytic results will serve as a basis for constructing an efficient closed-loop system for ICSN of the oil and gas resource-based urban EIPs.Through the stability analysis of the industrial coupling symbiotic network of the oil and gas resource-based urban eco-industrial park, it can determine the stability conditions that affect the overall performance of the industrial park. Studies have shown that increasing network stability and improving energy efficiency in the park can improve the overall sustainability of the eco-industrial park and accelerate the effective transformation of resource-based cities.
