Measurement and Coupling Coordination of High-Quality Development in Guangdong Province of China: A Spatiotemporal Analysis

Abstract

Regional high-quality coordination plays a crucial role in promoting high-quality national development. Guangdong province is a trailblazer in China’s reform and opening-up policies and high-quality development. This study analyzes the high-quality development of the economic, social, and ecological environments from 2010 to 2019 in Guangdong with the entropy weight TOPSIS model. Meanwhile, the coupling coordination degree model is used to investigate the spatial-temporal pattern of the coupling and coordinated development of the three-dimensional system in 21 prefecture-level cities. The results show that the high-quality development index of Guangdong increased from 0.32 to 0.39, a 21.9% increase during 2010–2019. The Pearl River Delta had the highest value of the high-quality development index, whereas Western Guangdong had the lowest level in 2019. Guangzhou, Shenzhen, Zhuhai, and Dongguan are the core cities in the high-quality development of Guangdong, with the index decreasing from the Pearl River Delta estuary cities to the province’s edge. We also found that the coupling degree and coupling coordination of high-quality development of the three-dimensional system grew slowly during the study period. Half of the cities in Guangdong entered the stage of benign coupling. Except for Zhaoqing, all cities in the Pearl River Delta have a high coupling coordination degree of high-quality development of the three-dimensional system. This study provides valuable references for the high-quality, coordinated development of Guangdong province and some policy suggestions for other regions.

Measurement and Spatio-Temporal Characteristics of High-Quality Development Efficiency in Metropolitan Areas: A Case Study of the Changchun Metropolitan Area

“…Pan et al believed that HQD is an efficient, fair, and sustainable development that stimulates the creativity and vitality of the whole society [23]. Hu et al and Li et al considered that HQD is multi-dimensional and part of a complex organic whole involving the economy, society, culture, and ecology [24,25]. Zhang argued that HQD entails satisfying the growing demands of individuals for an improved standard of living through enhancements in productivity and socio-economic advancement [26].…”

Exploring the prospective relationships between food addiction symptoms, weight bias internalization, and psychological distress in Chinese adolescents

“…Data for the present study were sourced from a longitudinal project on eating behaviors and body image in Chinese adolescents, which was approved by the Research Ethics Committee of the Chinese University of Hong Kong, Shenzhen. Three waves of data were collected at 6-month intervals from an urban high school in Guangdong province which is the most economically developed province in China (Hu et al, 2023). The project was introduced to the students by the head teachers of classes after obtaining approval from the school administrator.…”

Measurement and Spatiotemporal Dynamic Evolution of China's High-Quality Economic Development

“…However, one indicator hardly suffices to capture the entirety of high-quality economic development. While others constructed a multi-dimensional evaluation index system of high-quality development [15,16], Ma [17] (2022) designed an evaluation index system of high-quality economic development employing three dimensions of "economic development, social life, ecological environment." Moreover, Huang et al [18] established the evaluation index system of China's high-quality development from five aspects 2 such as innovation development, urban-rural coordination, ecological environment, opening to the outside world, and individuals' livelihood.…”
