摘要： 基于支付卡式条件价值法对广州市554个家庭进行问卷调查,考察珠江下游城市居民对改进的流域环境质量的支付意愿,并利用Tobit模型实证检验支付意愿的主要影响因素,结果表明:珠江下游居民具有正支付意愿的比例为91.52%,均值为4.62元/月。城市居民个体异质性是流域环境质量需求的重要影响因素,较高的收入水平显著提升其对清洁水源的支付意愿;从城市居民行为特征看,河边运动次数越多,对环境质量需求越大,从而支付意愿越高,同时,若家中已安装净水器,支付意愿则较低;另外,城市居民环境意识是流域环境质量需求支付意愿的显著影响因素。进一步的收入异质性检验表明,低收入群体的支付意愿更易受环境价值与外部性认知驱动,而高收入群体更显著受支付能力、净水器等替代性防护行为及迁移预期影响;调节效应结果显示,家庭净水器会显著削弱居民河流环境意识对支付意愿的影响强度。在改善流域水环境过程中,应增强流域下游城市居民对生态系统重要性的认知,并建立基于流域下游居民参与和付费的流域生态系统保护激励机制,从而全面提升上游水源区和下游居民区的人类福利水平。

Abstract: Based on the Payment Card Contingent Valuation Method, a questionnaire survey was conducted among 554 households in Guangzhou to investigate the willingness to pay (WTP) of urban residents in the lower reaches of the Pearl River for improved river basin environmental quality. The Tobit model was employed to empirically examine the main influencing factors of WTP. The results indicate that the proportion of residents in the lower reaches of the Pearl River with positive WTP was 91.52%, with a mean value of 4.62 CNY per month. Individual heterogeneity among urban residents constitutes a significant influencing factor on the demand for river basin environmental quality. Income level significantly enhances their WTP for clean water sources. Regarding behavioral characteristics, the more frequent the riverside exercise, the greater the demand for environmental quality and consequently the higher the WTP; meanwhile, households already equipped with water purifiers exhibited lower WTP. Furthermore, environmental awareness among urban residents significantly influences their WTP for river basin environmental quality. Further income heterogeneity tests reveal that the WTP of low-income groups is more easily driven by the cognition of environmental value and externalities, whereas that of high-income groups is more significantly affected by payment capacity, alternative protective behaviors such as using water purifiers, and migration expectations. Moderation effect results demonstrate that household water purifiers significantly weaken the impact intensity of residents’ river environmental awareness on their WTP. In the process of improving river basin water environments, it is imperative to enhance the cognition of urban residents in the lower reaches regarding the importance of ecosystems and establish incentive mechanisms for river basin ecosystem protection based on the participation and payment of these downstream residents, thereby comprehensively elevating the level of human welfare in both upstream water source areas and downstream residential areas.
