Study on the Coupling and Coordination Relationship between Gross Ecosystem Product (GEP) and Regional Economic System: A Case Study of Jiangxi Province

Abstract

The Gross Ecosystem Product (GEP) is an important way to assess the state of the ecosystem and to clarify the coupling and coordination between the ecosystem and the economic system, which can be a scientific basis for achieving the synergistic development of economic society and ecological civilization. In this paper, 11 prefectural cities in Jiangxi Province are taken as research areas. Based on the data of land use, normalized difference vegetation index, net primary productivity, soil, meteorology, elevation and statistics, the study accounts for the GEP in Jiangxi Province in 2010 and 2020 based on a biophysical model, and analyzes the changes of its ecosystem’s state. Based on the economic data obtained from the Jiangxi Statistical Yearbook, a regional economic index system was established; the levels of GEP and the regional economy were measured with the help of entropy-weight-TOPSIS method, and the interaction mechanism and coupling coordination dynamics between them were explored based on the coupling coordination degree model. It was found that during 2010–2020, the GEP in Jiangxi Province increased by 0.35%, and the value of material goods and cultural services increased by 49.57% and 414.03%, respectively, but the value of regulating services decreased by 9.89%; the main coupled and coordinated development characteristics of ecosystem and economic system in Jiangxi Province developed from basic coordination-economic lagging to moderate coordination-ecological lagging, and the coupled coordinated development continues to improve, but the development of gross ecosystem product lags behind the level of economic development.

Evaluation and Differentiation Analysis of China’s Construction of Ecological Civilization from the Perspective of Collaboration: Using China’s Representative Region as an Example

“…The coupling coordination model can reflect the intrinsic correlation strength of the system but cannot reflect the gap between systems. The relative development degree can be used to measure the degree of relative advance or lag development between systems [38]. Therefore, this study introduces a relative development degree to measure the advanced or lagging development subsystems in the multisystem of the construction of ecological civilization.…”

“…In this study, the social subsystem and the economic subsystem are regarded as a system in which the natural subsystem is used for comparison, and the average value of the social and economic subsystem score is compared with that of the natural subsystem when judged. The determination method of the ratio threshold is referred to by Xie et al [38]. The division criteria are shown as follows: the coordinated development features are a natural lag when the relative development degree is less than 2, the coordinated development features are balanced when the relative development degree is between 2 and 4, the coordinated development features are social and economic lag when the relative development degree is more than 4.…”

A Study on the Spatial Pattern of the Ecological Product Value of China’s County-Level Regions Based on GEP Evaluation

“…The calculation idea of the GEP is to calculate the functional quantity of each ecological element and then convert it into value quantity [ 20 ]. After receiving initial attention, GEP’s concept connotations, accounting framework and accounting methods were gradually clarified, and a number of local research practices emerged, forming a multi-level, multi-element GEP accounting case at the national [ 21 ], provincial [ 22 , 23 , 24 , 25 ], city [ 26 , 27 , 28 ] and county levels [ 29 , 30 , 31 , 32 ]. In 2021, the relevant methods of GEP evaluation were incorporated into the System of Environmental and Economic Accounting-Ecosystem Accounting (SEEA-EA) framework by the United Nations.…”

Evaluation of Gross Ecosystem Product in Taiwan Island and Analysis of Impact of Urbanization

“…The ecosystem is the material and spiritual homeland that humans depend on for survival. It can provide humans with many products and services, such as crops, fruits, wood, medicinal materials, as well as services such as flood storage, carbon sequestration, oxygen release, and water purification [1] . The services rooted from ecosystems not only serve as the foundation for human survival and development, but also play a crucial role in the Earth's life support system [2][3] [4] .…”
