Abstract

In recent years, the issue of nuclear wastewater treatment has garnered considerable attention. Investigating the specific impact mechanisms of nuclear pollution on the development of the seafood industry holds significant importance for national economic development. Based on this premise, this study first examines the influence of nuclear wastewater discharge from Country J on the willingness of City Q’s residents to purchase seafood through a comparative survey. Then, a DID (Difference-in-Differences) model and a SARIMA (Seasonal Autoregressive Integrated Moving Average) time series model are constructed to analyze the impact mechanisms of nuclear pollution discharge on the seafood economy. The empirical results indicate that Country J’s nuclear wastewater discharge practices negatively affect the cumulative growth rate of sales in City Q and also reduce residents’ willingness to purchase seafood. Based on these findings, this study provides relevant policy recommendations for policymakers and stakeholders in the seafood industry to address potential environmental and economic challenges in the future.
