Negative Sentiment Modeling and Public Legal Liability from Urban Green Space: A Framework for Policy Action in China

Abstract

This paper intends to optimize the urban green space (UGS) management and implementation strategies by analyzing climate change models and reviewing economic, energy, and public health policies. This paper studies the public perception of climate change-induced public health emergency (PHE) in China by surveying online public comments. Specifically, it looks into public health perception, anxiety perception, relative deprivation, and emotional polarity from public online comments. The following conclusions are drawn through the empirical test of 179 questionnaires. The findings revealed that health risk perception has a positive predictive effect on relative deprivation and anxiety perception. The higher the health risk perception, the stronger the relative deprivation and anxiety are. Anxiety perception and relative deprivation have mediating effects in the model. In addition, the main research method adopts a questionnaire survey. The mediating effect between each variable is further studied. This paper analyzes the citizens’ right to health and public health protection under climate change, and explains public risk perception and anxiety perception. Meanwhile, the evaluation cases are used to analyze the public health and UGS construction strategies to suggest climate compensation laws and improve the urban greening rate. This finding has practical reference value for promoting the deep integration of UGS and public health. It can promote the development and planning of UGS under climate change and biodiversity loss and has significant reference value for improving negative emotions and the public legal liability system.
