Based on the tourism industry economic panel data, this research divides and measures the tourism industry’s economic resilience cycle in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) by constructing a counterfactual function and exploring the evolution of its Spatial-Temporal difference characteristics in the past 20 years. Estimation results show that three out of the four Recession–Recovery cycles of GBA have been characterized as “creative destruction”. Moreover, the economic resilience values and fluctuation trends of the individual tourism industries in the GBA are quite different. Additionally, the economic resilience of the urban tourism industry has changed from centralized to discrete, and the trend of economic resilience of the tourism industry has changed from low toughness to concentrated. This study expands the practice of resilience theory in the tourism industry economy, and it reveals the difference of tourism industry resilience in the metropolitan area system of GBA urban agglomeration from the perspective of industrial economic resistance and resilience.

The orderly development of diverse rural industries affects sustainable development in China. This study offers new insight in that the three-industry integration leads the rural economy as a whole system, with the integration between different industries affecting not just a single industrys development but also the sustainability of multiple rural industries. Conghua District is taken as an example in this research, and selected indicators and data from the past 14 years are obtained from the Conghua Statistical Yearbook. The density dependence logistic model is adopted to analyze the symbiosis patterns of rural three-industry integration system (RTIIS). The findings reveal that the symbiosis between the primary industry and the secondary industry in Conghua is poor, resulting in a negative symbiosis relationshipnamely, the mode of mutual competition. However, the symbiotic development model appears to reveal a positive, asymmetrical relationship (mutualism) between primary industry and tertiary industry and between secondary industry and tertiary industry. This study explores the process of rural three-industry integration through to the stage of symbiosis and provides scientific research methods and directions for the sustainable symbiosis of RTIIS. Future research on RTIIS in the framework of symbiosis theory will be of higher theoretical and practical value.

With the continuous improvement in the integration of urban agglomeration, a multi-functional, socialized, and complex dynamic system, effective prevention and control of emergent public health events have become increasingly important. Based on the Public-Health Vulnerability-Assessment-System of Urban Agglomeration (PVUA), the temporal and spatial differentiation characteristics of vulnerability in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) for the period of 2015-2019 are explored, and the vulnerable cities to public health events are identified in this area. The results can be summarized as follows: (1) The overall vulnerability to public health events in GBA decreases in the investigated period. (2) In the temporal dimension, accompanied by social and economic development, the sensitivity to public health events increases in GBA, and the coping capacity change from stable fluctuation to rapid improvement. (3) From the spatial dimension, the sensitivity level in GBA is low in the west, relatively high in the middle, and high in the southeast; the coping capacity is high in the southeast and low in the northwest; the collaborative governance capacity presents a spatial pattern of being low in the south and high in the north. (4) In the period of study, the vulnerability to public health events in Guangzhou and Jiangmen is stable at the lowest level, while that in Zhaoqing, Foshan, and Hong Kong SAR (Special Administrative Region) gradually reduces; the vulnerability in Shenzhen, Zhuhai, and Dongguan is fluctuating, and that in Huizhou, Zhongshan, and Macao SAR is continually maintained at a higher and the highest level.
