Multi-Scale Evaluation of Suzhou City’s Sustainable Development Level Based on the Sustainable Development Goals Framework

Abstract

A sustainable development system involves resource limitation, environmental stress and policy regulation, and the flow and integration of resources and factors on a multi-level spatial scale. However, it is difficult to meet the actual needs of local development through traditional single-scale and macro-scale evaluation of the comprehensive level. Taking Suzhou City as an example, based on the United Nations (UN) sustainable development goals (SDGs) framework, the entropy method and fuzzy comprehensive evaluation (FCE) were used to construct an evaluation index system of the municipal sustainable development level. Growth and obstacles of the sustainable development system and its subsystems were systematically analyzed on a multi-level spatial scale. Results show that during the study period (2000-2016), the sustainable development system in Suzhou was relatively low at the beginning of the study. With the passage of time, it generally developed in a stable, continuous, and balanced direction. The levels of development, deficiencies, and obstacle factors of sustainable development systems and their subsystems are significantly different between levels; especially during the study period, the order change between towns is significantly higher than the order change between districts. Within an evaluation unit, there is a process of rising and continuing growth among certain subsystems, but some subsystems have been developing slowly due to resource constraints, environmental load, etc., or their contribution to the level of sustainable development has remained low. The city sustainable development evaluation index system based on the SDGs framework can meet the requirements of regional assessment and has the potential for further promotion and use. The evaluation results can provide a necessary reference for the subsystem coordination, scale linkage, and resource space allocation of the sustainable development system in Suzhou.

Travel mode choice for domestic intercity travel: A case study in Suzhou, China

“…This study uses Suzhou as a case study to examine domestic intercity travel within Mainland China to capture different perspectives on why residents there choose different travel modes. Suzhou is an ideal study location because it has a highly developed HSR network (Wang et al, 2020;Zhou & Zhang, 2021), has three airports nearby (Shanghai Hongqiao, Shanghai Pudong, and Sunan Shuofang), a population of over 10 million, and has experienced rapid economic development and subsequent increases in demand for intercity travel (Chung et al, 2020;Lin et al, 2020). Thus, this study aims to contribute to the literature through the use of different instruments for data collection and through using a single city as the study location.…”

Exploring the Differences of Sustainable Urban Development Levels from the Perspective of Multivariate Functional Data Analysis: A Case Study of 33 Cities in China

“…For instance, Wei et al [40] assembled 54 variables and associated thresholds into an urban carrying capacity evaluation framework to examine Beijing's ability for sustainable growth. Lin et al [41] calculated the sustainable development level of Suzhou City in the target years (2000,2005,2010, and 2016) based on the constructed evaluation index system of sustainable urban development combined with the entropy-fuzzy comprehensive evaluation method. Tang et al [11] established an evaluation index system that includes 39 economic, social, and environmental indicators to evaluate and rank the sustainable development level of 16 cities in Anhui Province in 2017.…”
