Regional Economic Growth and Energy Consumption Intensity Differences Based on DEA's Empirical Analysis

Abstract

Today, China's economy is growing faster and faster, the consumption of resources has gradually increased, the relationship between supply and demand of resources is tight, and the pressure of public opinion at home and abroad is also increasing. The purpose of this article is to analyze the differences between regional economic growth and energy consumption intensity based on DEA's empirical analysis, and to use the method of data envelopment analysis to study energy consumption, developed and underdeveloped regions respectively. Regional economic growth is represented by the Gini coefficient, and energy consumption intensity is represented by an index. All three regions were analyzed using a parameter-invariant panel data model. After comparative analysis, there are regional differences in my country's economic development and energy consumption, but these differences do not completely correspond. From 2017 to 2021, the differences between the three regions in my country generally showed a downward trend, and the development gap (Gini coefficient) between the three regions reached a peak of 0.27 in 2019. The energy consumption intensity of various regions shows a downward trend, but from 2019 to 2021, the energy consumption intensity of developing regions has increased in a small range, while other regions are basically in a stable trend at this stage.
