Against the backdrop of escalating climate change, the effectiveness of risk communication for urban rail transit systems under extreme weather events such as rainstorms has emerged as a critical issue in urban resilience building. Focusing on the risk communication challenges faced by urban rail transit in rainstorm scenarios, this study systematically extracts eight categories of core factors through a three-level coding process based on grounded theory. Building on this, the Analytic Hierarchy Process (AHP) is employed to quantitatively assess the importance of each influencing factor. The theoretical model developed in this research not only enriches the research framework in related fields but also provides a theoretical foundation and practical guidance for optimizing risk communication mechanisms in urban rail transit under extreme climatic conditions.

This paper reviews the development of Macao’s marine economy over the 25 years since its return to China, with a particular focus on its economic structure, industrial layout, future development potential, and possible challenges. Although Macao is a coastal city endowed with relatively abundant marine resources, the development of its marine economy has lagged behind. By analyzing the current state, opportunities, and challenges of Macao’s marine economy, this study explores how policy support and technological innovation can be leveraged to promote its sustainable development.

The green finance reform and innovation pilot zone policy aims to alleviate financial constraints on green technological innovation along the new energy vehicle (NEV) industry chain through diversified financial instruments. Based on data from listed NEV companies on the Shanghai and Shenzhen A-share markets from 2012 to 2022, this study uses a quasi-natural experiment involving three batches of pilot zones (established in 2017, 2019, and 2022) to construct a staggered difference-in-differences (DID) model to assess the policy's impact on green technological innovation. Results show that the pilot zone policy significantly promotes green technological innovation among NEV-related enterprises. The policy indirectly drives innovation by increasing R&D investment. However, financing constraints weaken the policy’s effects, while firms with stronger financing capabilities benefit more. The policy impact is more pronounced for state-owned and central-western enterprises. This study provides three key insights for optimizing green finance policy: addressing financing difficulties of non-state-owned enterprises, improving the financial support system, and implementing regionally differentiated support strategies.
