Decoding of Typhoon Emergency Policy in Coastal Cities: Policy Text Mining From China

Typhoon emergency policies are a crucial safeguard for the sustainable development of global cities. However, the extent to which these typhoon emergency policies are effective or deficient, and how they impact the practical outcomes of typhoon emergency responses, still lacks in-depth research. This study focuses on typhoon emergency policies in China's coastal cities, employing an improved policy consistency model to construct policy evaluation indicators for quantitative assessment, and conducts comparative analysis with national, provincial, and inland cities' typhoon emergency policies. The study found that: (1) The policy consistency evaluations of P1, P2, P3, P9, P10, and P11 are at the perfect level; the policy consistency evaluations of P4, P5, P6, and P8 are at the excellent level; and the policy consistency evaluation of P5 is at the acceptable level. (2) The typhoon emergency policies of national-level, provincial-level, and inland cities performed well in the evaluation, while coastal cities showed deficiencies, generally following the differential order pattern of government governance. (3) Typhoon emergency policies can effectively function in practice. This study provides a reference for other coastal cities to improve typhoon emergency policies and optimize typhoon emergency management systems, holding significant practical implications.
