# The sustainability of recreational sports in Chinese cities based on cognitive entropy

## TL;DR

This paper studies how recreational sports can be sustained in Chinese cities like Hangzhou, Shanghai, and Chengdu using cognitive entropy and evaluation methods.

## Contribution

A novel approach to assess recreational sports sustainability using cognitive entropy and TOPSIS method in urban planning.

## Key findings

- The RS system consists of five subsystems and is evaluated using 28 indicators.
- Questionnaire validity was confirmed with good fit using factor analysis and structural modeling.
- Cognitive entropy and TOPSIS method revealed sustainability levels and urban planning suggestions for the three cities.

## Abstract

With progress of science and development of economy, increasing numbers of urban residents take part in recreational sports (RS) due to their more leisure time and increased income. The RS is defined as a kind of physical activities engaged by people during their leisure time for obtaining experience of physical and mental pleasure. The sustainability of the RS plays a critical role in sustainable urban development. As major Chinese cities, such as Hangzhou, Shanghai and Chengdu, are faced with how to maintain sustainable development of their RS systems, which are selected as case cities for empirical analysis. The RS system and its evaluation indicators are constructed by using the conceptual composition method. The RS system is made up of five subsystems including the industrial subsystem, space subsystem, experience subsystem and formal subsystem. The indicator system for assessment of RS system is included 28 indicators. The validity of the RS system questionnaire is tested by employing confirmatory factor analysis and structural equation modeling software. The result indicates good fit of the questionnaire factors. The inquiry was carried out in the three cities where 1080 residents were approached and 1028 questionnaires were collected. The cognitive entropies and weight matrix for the RS system of each sample cities are calculated based on entropy theory. The sustainable development levels of each subsystem of the RS system are obtained by using TOPSIS Method. Then, suggestions of urban planning for three cities have been derived by the results of analysis based on their historical background, regional characteristic and development level.
