1. Introduction
China’s sports industry has made great progress since China’s reform and opening up in 1979. The report of the 19th National Congress of the Communist Party of China pointed out that “extensive nationwide fitness activities should be carried out to accelerate the construction of a strong sports country”. Therefore, comprehensive fitness has become China’s national strategy. Expanding and strengthening the sports industry is an important measure to speed up the construction of a strong sports country, promote high-quality economic development, and realize people’s yearning for a better life. In recent years, China has begun to attach great importance to the healthy and sustainable development of the sports industry. In October 2014, the Chinese government issued several opinions on accelerating the development of sports industry and promoting sports consumption, which include promoting the healthy development of characteristic sports, accelerating the integration of fitness and leisure and related industries, and optimizing the structure and layout of fitness and leisure industry [

In October 2016, the Chinese government issued the outline of “Healthy China 2030” plan, which puts forward promoting the construction of a healthy China, integrating health into all policies, further optimizing the market environment of the sports industry, cultivating multiple subjects, and actively developing the fitness and leisure industry [

In 2018, the China Sports Industry Development Conference elaborated on the existing problems and future development direction of China’s sports industry and gave guidance on how to develop ice and snow industry in a more orderly and healthy way, comprehensively boosting the construction of sports power. Therefore, the timely diagnosis of the problems and shortcomings in China’s sports industry and the scientific evaluation of the healthy development level of the sports industry can help to predict the development trend of the sports industry and grasp the development characteristics of the sports industry so as to formulate reasonable measures for the high-quality development of the sports industry and help build a healthy China and a strong sports country.
Health degree is the representation of human health and a quantitative index to measure the health degree of the human body. Leopole [
3] and Woodwell [
4] introduced health degree into natural ecosystems, mainly on the basis of quantitative evaluation and analysis of islands, water bodies, wetlands, deserts, and plants, based on mathematical models including quality index method, fuzzy mathematics method, and cluster analysis method, so as to improve the diversity and balance of the development of natural ecosystems. With people’s continuous acceptance and cognition of the concept of sustainable development, the application of health has begun to change, from the original application of the pure natural ecosystem to the natural social composite system. Many scholars use set pair analysis [
5], Pressure-State-Respons (PSR) model [
6] and emergy evaluation [
7] to analyze the health status of agriculture and urban ecosystem from the aspects of vitality, ecological potential, living state, and vitality, so as to promote the coordination of human land relationship. In the 21st century, the academic community began to pay close attention to the research of pure social system health and the literature about health is not limited to the natural social composite system and pure natural ecosystem. For example, based on the analysis of the connotation and composition of the growth health of enterprises, Lou [
8] established the evaluation index system and evaluation model of the growth health of innovative enterprises and conducted empirical research. Xie [
9], Li [
10], and Wang [
11] conducted research on market health, information system health, brand health, etc.
In recent years, scholars have begun to pay attention to the health of industries, but there are few related studies, mainly focusing on the financial industry, real estate industry, and health industry [
12,
13,
14]. With regard to the healthy development of sports industry, Shen [
15] proposed realizing the healthy and sustainable development of sports industry, which should be guided by the five new development concepts of “innovation, coordination, green, opening and sharing” proposed by the Fifth Plenary Session of the 18th CPC Central Committee, and promoting the supply-side structural reform of the sports industry. Shen [
16] believed that China’s sports industry ushered in a golden development period, and the supply-side reform of the sports industry in the context of the new normal economy is an objective need to ensure the healthy and sustainable development of sports industry. Liu [
17] analyzed the deep mechanism, construction mode, and influencing factors of the deep integration of the health industry and the sports industry. These documents have important theoretical reference value for the healthy development of China’s sports industry, while the quantitative research on the health evaluation of the sports industry has not been carried out.
There are some relevant research focuses on the sustainable development of the sports industry and the competitiveness of the sports industry. For example, Lindsey [
18] studied the relevance of the sustainable development goals across diverse sectors of the sport industry and illustrated complexities within and across countries that make pursuit of comprehensive policy coherence infeasible. Zhao [
19] studied the optimization strategy of the ice and snow sports industry for sustainable development. Li [
20] adopted the method of systematic analysis and qualitative analysis, applied the mixed-method paradigm of correlation analysis, prediction analysis and grounded theoretical analysis, and explored the dynamic model of ski industry chain correlation and prediction effect and sustainable development of ski industry. Ren [
21] constructed the evaluation index system of sports industry competitiveness and conducted factor analysis on the competitiveness of China’s sports industry from 1996 to 2013. Sun [
22] used matter-element model to build a two-dimensional evaluation system of sustainable competitiveness of the provincial sports industry composed of “development degree sustainability” to comprehensively measure the competitiveness level of China’s Provincial Sports Industry.
Although much progress has been made, there is little research on the sustainable development of the sports industry from the perspective of the health degree of the sports industry. Additionally, the sports industry is regarded as a strategic pillar industry in China [
23], and the sustainable development of the sports industry has an important role on the construction of ecological civilization, while the research on the health degree of China’s sports industry has not been carried out yet, and the evolution characteristics and laws of the healthy development of China’s sports industry are still not clear. Therefore, it is essential to analyze the current situation and prospects of the healthy and sustainable development of China’s sports industry.
In this paper, to explore the current situation and future trend of the healthy development of China’s sports industry, the health evaluation index system of the sports industry was established by deconstructing the health dimension of the sports industry. The health evaluation model of the sports industry was constructed by using the entropy method and the multi-objective linear weighting method. The model was used to empirically analyze the characteristics and laws of the health of China’s sports industry from 2008 to 2017 and predict the health status of China’s sports industry in the next 10 years with the combination with the grey model (1.1), i.e. GM(1.1) model. On the basis of deconstructing the health dimension of China’s sports industry, this paper intends to build the health evaluation index system of sports industry, use a multi-dimensional evaluation model to analyze the health of China’s sports industry in 2008–2017, and predict and analyze the health status of China’s sports industry in the next 10 years, in order to provide reference for China and other countries’ sports industry to improve quality, increase efficiency and transform development.
