The high-quality development of the service industry has increasingly become an important part of the high-quality development of the economy. On the basis of combing the literature of high-quality development of service industry, this paper deconstructs the high-quality development of service industry into four parts: high-quality structure, high-quality benefit, high-quality scale, and high-quality brand, and then constructs the evaluation index system of high-quality development of service industry. Furthermore, according to the index system, the high-quality development of China’s service industry is estimated in general, classification and regions, and it is found that the high-quality development of China’s service industry presents a trend of overall rise, brand stagnation, and regional imbalance. Finally, the study finds that China’s service industry can achieve better and high-quality development through four paths, namely, structure optimization, brand reengineering, integrated development, and coordinated development. The research in this paper is a useful attempt to evaluate the quality development index of the service industry and has certain policy implications on the high-quality development of the service industry.
