Abstract: Based on the theoretical mechanism of "institutional pressure-organizational response", this study takes 30 provincial governments in China as cases and uses the qualitative comparative analysis method to explore the causal mechanism and driving path of regional environmental performance. The findings are as follows: First, no single factor can constitute a necessary or sufficient condition for high-level environmental performance. There are four categories of conditional configurations that constitute the driving paths to achieve high levels of environmental performance. Second, the effective combination of the factors from both institutional pressures and government response can improve environmental performance in the way that "all paths lead to the same goal". Third, substitutions and synergies between formal and informal institutional pressures, and the matching relationship between institutional pressure and local government response illustrate the linkage matching model for achieving high environmental performance. The conclusions of this study are helpful in deepening the rational understanding of the nature of complex interactions between multiple factors behind regional environmental performance and provide useful practical inspiration for local governments' environmental governance.

摘要： 研究基于“制度压力—组织响应”的理论机制，以我国30个省级政府为案例，运用定性比较分析方法，探讨区域环境绩效的因果机制及驱动路径。研究发现：第一，任何单一因素均无法构成高水平环境绩效的必要条件或充分条件。四类条件组态构成了实现高水平环境绩效的驱动路径。第二，制度压力和政府响应条件多重并发，以“殊途同归”的方式提升环境绩效。第三，正式制度压力与非正式制度压力之间的替代和协同关系，制度压力与当地政府响应之间的匹配关系，阐释了实现高水平环境绩效的联动匹配模式。研究结论有助于深化我国区域环境绩效背后多重因素间复杂互动本质的理性认识，并为地方政府环境治理提供有益的实践启示。
