Drawing from the perspective of motivation-behavior relations, this study explores whether self-transcendent and activating status motives trigger pro-environmental behavioral intentions of residents living nearby urban parks. Meanwhile, this study particularly examines the moderating effect of community social capital and whether there exists an incompatibility between community social capital and personal motives. This study adopts Hierarchical Linear Modeling (HLM) method to conduct data analysis and reveals that self-transcendent and activating status motives positively influence nearby residents' pro-environmental behavioral intentions. The relationships between personal motives and pro-environmental behavioral intentions are negatively affected by community social capital, suggesting that there is an incompatibility between community social capital and personal motives. Furthermore, a positive spillover effect between low and high effort pro-environmental behavioral intentions is noted. These findings provide park and community managers with insights as far as the residents' engagement in urban park sustainability is concerned.
