The Yangtze River Delta urban agglomeration is the leading and demonstration area for the high-quality development of culture tourism (HDCT) in China. It is of great significance to study the spatiotemporal characteristics and impact mechanism of the HDCT for revealing the internal law of HDCT and promoting the collaborative innovation of culture tourism among cities. Based on the scientific construction of the evaluation system of HDCT, this paper made a quantitative analysis of 26 cities’ HDCT by using coupling coordination degree model, Lisa spatiotemporal transition and spatial Durbin model (SDM). The results show that: The overall level of 26 cities’ HDCT shows a fluctuating upward trend, and presents a "Z" pattern in space. More than 80% of the cities are at the medium and high level. Shanghai has obvious advantages in the primacy degree. There is a significant positive spatial autocorrelation among cities with high-quality of culture tourism development. The spatial clustering and proximity of the same kind are increasing, and the radiation effect is gradually obvious. The local spatial association patterns are mainly HH and LL agglomeration, and the characteristics of polarization are gradually prominent. The local spatial correlation structure of HDCT has strong stability, the transfer inertia between types is prominent, and the overall spatial evolution is lack of integration with obvious path dependence and lock-in effect. The spatiotemporal evolution of the HDCT is a complex process under the interaction of multiple factors, and there is a significant spatial spillover effect (0.256). The level of economic development, technological innovation, professional talent allocation are the three main factors. According to the dominant factor, it can be divided into economy stabilizing type, industry optimizing type, innovation driving type and traffic impacting type. These findings have implications for local governments and tourism management departments to achieve high-quality innovative development of cultural tourism.

A number of studies have been carried out on the importance and connotation of tourism culture. However, from the literature study of tourism culture, it is found that there is still a gap between the remolding of tourism culture and the development of tourism enterprises in the digital era. This study aims to identify the enterprise clustering effect and employment benefit of rural tourism culture reshaping. By empirical research, this study establishes a new conceptual research framework for rural tourism sustainability to cover the gap between the cultural reshaping and enterprise development for rural tourism in Zhejiang. We began with investigation to villagers on their acceptance of reshaped tourism culture. Through interviews with entrepreneurs, this study investigates the relationship between tourism cultural reshaping and tourism enterprise image. An enterprise network of regional tourism cultural IP image has been established to describe the density among the whole tourism cultural industry. The location entropy index is adopted to show the employment in tourism enterprises. This index reflects residents’ acceptance of the reshaped cultural image as a key influencing factor of enterprises’ sustainable development. Furthermore, it is found that tourism cultural reshaping is a significant base for rural tourism industry clustering. The research results suggest that tourism corporation can contribute to the local tourism economy by reshaping culture.
