With the emergence of the Lewis Turning Point and the disappearance of Demographic Dividend, improving production efficiency has become an important issue in China. As a special type of enterprise in China, university spin-offs have both the elements of a state-owned economy and market economy. As the dual attributes of university spin-offs study the effect of enterprise ownership structure and staff structure on labor productivity, this becomes a critical issue. Based on the data of 151 university spin-offs in Hubei Province of China in 2017, this paper constructs a multiple regression model to analyze the impact of property rights and staffing on the labor productivity of employees. The results suggest that the coexistence of multiple staffing structures of university spin-offs is not only detrimental to their own development but also weakens the positive effect of clear property rights on labor productivity. Clarifying the property rights, reducing the number of public institution staff will lead to reforms of the university spin-offs in the future.

The economic linkages between cities within the Yangtze River Economic Belt city cluster are important for precisely implementing the Yangtze River Economic Belt strategy. Accordingly, this study used the revised gravity model, social network method, and spatial Durbin model to analyze the economic linkage strength, spatial-temporal differentiation, and driving factors of the three major city cluster in the Yangtze River Economic Belt from 2006–2020. The results confirm that the Chengdu-Chongqing urban agglomeration has formed a network structure with Chengdu and Chongqing as the two poles; the urban agglomeration in the middle reaches of the Yangtze River has formed a point-axis development pattern of Wuhan, Changsha and Nanchang. The Yangtze River Delta urban agglomeration formed a multi-center radiation and sub-network development pattern. Additionally, the characteristics of network structure significantly affected the flow of factors, the level of economic development was the basis for strengthening communication and cooperation between cities. Meanwhile, the advanced industrial structures played an important role in promoting industrial linkages, and human capital exerts an obvious spatial spillover effect. Therefore, these three major urban agglomerations should implement differentiated development strategies and enhance the synergy of their linkage networks, thus promoting high-quality development.
