Influencing Factors and Their Influencing Mechanisms on Integrated Power and Gas System Coupling

Abstract

In order to study the deep mechanism of integrated power–gas system (IPGS) coupling, the influencing factors of IPGS coupling are investigated using the Decision Making Test and Evaluation Test–Interpretative Structural Modeling–Method-Cross-Impact Matrix Multiplication Method (DEMATEL-ISM-MACMIC). By means of a literature review and field research, on the basis of summarizing and forming an index system of IPGS coupling influence factors, this study establishes an IPGS coupling influence factor model based on the DEMATEL-ISM-MACMIC method, analyzes the attribute characteristics of each factor influencing IPGS coupling and extracts the key elements, explores the logical relationships among the factors, and finally, puts forward relevant suggestions, in order to provide theoretical and methodological support for this field of research. This study shows that the economic base, resource endowment, and economic and social development of the country are the most important factors. The study shows that the bottom-level factors, such as economic base and resource endowment; the middle-level factors, such as energy structure and market mechanism; and the surface-level factors, such as technology level and market price, are important factors influencing IPGS coupling, and the focus should be on the above factors.
