Exploring the mechanism and constraints of Green Finance on high-quality economic development is of great significance to achieve the strategic goal of carbon peak and carbon neutral. Based on the panel data of 30 provinces in China from 2009 to 2019, this paper uses the epsilon-based measure model and entropy method to measure the total factor rate of green economy and the development level of green finance. It then brings green finance, technological innovation, industrial structure upgrading, environmental supervision and high-quality economic development into a unified research framework for the first time. By constructing a panel two-way fixed effect model, regulatory intermediary effect model and threshold effect model, this paper empirically tests the action mechanism and constraints between green finance and high-quality economic development. The results show that: (1) The spatial evolution of green finance in China presents a gradient decreasing pattern from east to middle to west, coastal to inland, and the spatial evolution presents an obvious southwest-northeast pattern. (2) Green finance does have a significant role in promoting high-quality economic development, in which technological innovation and industrial structure upgrading play a part of the intermediary role. This conclusion is still valid under the robustness test of lagged explanatory variables and after the possible endogenous problems are alleviated by the difference-in-difference model (DID). (3) Environmental regulation plays a non-linear regulatory role in the relationship between green finance and high-quality economic development, and there is a single threshold value. Too high intensity of environmental regulation will weaken green finance, resulting in the innovation compensation effect being more diminutive than the circular cost effect. At this time, the high-quality economic development presents a state of diminishing marginal benefits.

Based on the support of governmental policies and the rapid growth of China’s economic development, residents’ living standards, and tourism consumption demand, cruise tourism has continuously developed and its service level has gradually improved, which have become the main driving forces for the sustainable growth of China’s cruise tourism industry. This paper took Shenzhen Shekou Port (SSP) as a research site and used an online text analysis method by Rost Content Mining 6 software to analyze 2552 Ctrip travel network, and then did further study through face to face interviews from the perspective of “tourists source” and “procurement” in the value chain theory. Only by understanding the developing trend of cruise tourists can we cultivate cruise culture, expand cruise tourism market, and finally realize the benign development of cruise tourism. The research results show that the cruise business in Shenzhen should strengthen the senior citizens market and marketing to kids and parents, and improve the satisfaction of cruise passengers in terms of enriching entertainment facilities, elevating service quality, and upgrading duty-free shopping centers. This paper not only focused on the study of cruise tourists in Southern China, but also enriches the research of the cruise value chain.

The convergence of sports and tourism industries is a vital direction for the coordinated development of industries, and a vital means to build a quality life circle suitable for living, working and traveling in the urban agglomeration of the Guangdong–Hong Kong–Macao Greater Bay Area (GBA). By using the coupling coordination degree model and exploratory spatial data analysis and establishing an evaluating indicator system for the converged development of sports and tourism industries, this paper measures and analyzes the convergence development level, spatial-temporal evolution, and spatial correlation of the two industries in 11 cities of GBA from 2011 to 2020. The results showed that the synthetical development level of the two industries in urban agglomeration of GBA was steadily rising, with significant differences in regional development, showing the east coast of GBA > the north coast of GBA > the west coast of GBA. The growth trend of industrial convergence degree is obvious, but the overall coupling coordination degree is not high, basically in the late maladjustment stage and transition stage. The convergence of the two industries shows a positive aggregation distribution in space, and the degree of agglomeration is rising. Cities around the Pearl River Estuary mostly belong to the “high-high” spatial association type, with obvious spillover effect, and become a significant growth pole for the converged development of the two industries in GBA. Cities in the periphery of GBA and the west coast of GBA mostly belong to the “low-low” and “low-high” spatial association types. Finally, sustainable development strategies are put forward from four aspects: spatial layout coordination, industrial division coordination, exchange platform coordination, and regional policy coordination, so as to promote the highly converged and coordinated development of the sports and tourism industries in the urban agglomeration of GBA.

Based on the theory of embodied cognition and questionnaire method, through the analysis to characteristics of honeymoon travel consumption and their internal and external influencing factors, as well as the survey of the need for experiential honeymoon tourism, this paper proves that the honeymoon tourism market under the background of experiential tourism should be developed to high-quality standard with a full-service focus on the purpose of creating a private, customized honeymoon tour with deep experience, strong individuality, specific theme, and integrating wedding-related situational experiences and it promotes resources integration and experience diversification development.

Taking Guangdong Province as an example, the article established the evaluation indexes of sports industry and tourism industry, and made use of entropy weight method and integration degree model to estimate integration development level during 2010 to 2016. The results demonstrate that the integration development of sports industry and tourism industry is general better, but the problem of incoordination and out-sync is prominent. Overall, the development grade of two kinds of industry convergence is relatively low, sports industry generally late than development of tourism industry, and it is in the phase of verging exclusion to the primary integration. In the future, the effective integration of customer demand and industrial transformation need, strengthening the conformity of sports industry and tourism industry from the two aspects of the industry and the government, will be the key to improve the convergence development level of two kinds of industry.
