Abstract: By expanding and innovating Michael Porter Diamond Model, a Dual-core Diamond Model is developed in this paper with innovation and openness as the core factors in consideration of the actual needs of the development of service sector in the Yangtze River Economic Belt of China. This paper establishes an evaluation indicator system of service sector competitiveness profitability to measure and evaluate the competitiveness of service sector in 11 provinces and towns in the Yangtze River Economic Belt through PCA (principal component analysis) based on the relevant information of the 11 provinces and towns mentioned above in 2015 and 2016. The research results indicate that the design of Dual-core Diamond Model is in line with the current situation and future development needs of the service sector in the Yangtze River Economic Belt, and the dual-core factors, namely, innovation and openness, have become the most important factors influencing the competitiveness of the service sector in the Yangtze River Economic Belt. Based on the model analysis results, it should propose strategies to enhance the competitiveness of the service industry in the Yangtze River Economic Belt. It needs to enhance innovation ability as well as to further expand trade in services. Firstly, encourage the growth of related industries and create a coordinated development cluster for the service sector. Second, intensify efforts in talent cultivation and build a talent system in alignment with the development of service sector. Third, improve the relevant legal system and innovate the service supervision and governance system in the service sector. Last, focus on a coordinated and integrated inter-region development.
