Academic entrepreneurship spans two different environments, academic and industrial. Therefore, academic entrepreneurs often shoulder the roles of scholars and entrepreneurs. Their social capital and perception of role conflicts will have a certain impact on the entrepreneurial process. Based on the theory of resource conservation, the expansion strengthening hypothesis, and the resource-based theory, a model was constructed to integrate the perception of role conflicts among academic entrepreneurs and the inertia of social capital on the acquisition of entrepreneurial resources and entrepreneurial performance. The moderating role of enterprise participation in this process was explored in depth. Based on the empirical data of 394 academic entrepreneurs, and using multiple regression analysis methods to conduct empirical testing, the results indicate that role conflict perception has a significant positive impact on resource acquisition and entrepreneurial performance. Social capital inertia has a significant negative impact on resource acquisition. Meanwhile, resource acquisition has a significant positive impact on entrepreneurial performance, and scholars' level of corporate participation positively moderates the relationship between role conflict perception and entrepreneurial performance. The above research results enrich the relevant research on the dual role of academic entrepreneurs from a subjective perception perspective, and also provide practical guidance for scholars who have entrepreneurial ideas or are already in the entrepreneurial process.

Based on the panel data of 35 large and medium-sized cities in China from 2008 to 2016, Tobit model and input-oriented data envelopment analysis (DEA) method was used to explore the impact of urban housing sales price on urban total factor productivity. It is found that in the overall dimension, the urban housing price and urban productivity present an inverted U-shaped curve, which increases first and then decreases. The urban housing price level exceeds the maximum critical value of "Houses are for living in, not for speculation", and the inhibiting effect of housing price rise on urban total factor productivity is significant. The effect of housing price on the productivity of cities with different population sizes is heterogeneous. When the city population size reaches the standard of the very large-sized city, the housing price and urban productivity show an inverted U-shaped feature, and when the city population size reaches the standard of the super large-sized city, the inverted U-shaped feature of housing price and urban productivity disappears. The inverted U-shaped relationship between housing prices and urban productivity in different types of cities and the heterogeneity of cities indicate that China's large and medium-sized cities should carry out the fine adjustment of housing prices, and the policy positioning of "Houses are for living in, not for speculation" has a solid theoretical basis and practical necessity.
