行政边界区域环境治理面临广泛的不良府际竞争、地方政府缺乏区域环境保护的内生动力、相关利益主体缺位、缺乏区域环境治理的长效机制等根本性困境。因而，区域环境治理内在地要求实行“协同法治”。区域环境“协同法治”的基本法理包括其核心内涵和基本要素两方面。其核心内涵包括以区域民生为本、区域权力的有序规束以及区域利益的动态均衡三方面；其基本要素包括实质要素和形式要素。实质要素包括：法律至上，法、理、情相得益彰；整体政府和责任政府；公民主体，区域社会共治。形式要素包括：协同性立法；区域内协同执法；权威的区域司法和多元区域解纷机制。

英文摘要：

Regional environmental management in administrative boundaries now are restricted by bad competition, lack of inner drive force ofenvironmental protection of local governments, absence of relevant interest subjects, and lack of longrun mechanism of regional environmental management, so it is important to coordinate relevant regions to rule by law. The legal basis of the principle of coordinate rule by law includes two aspects, e. g. the core connotation and the basic elements. The core connotations con tain the three aspects of livelihoodorientation,orderly restriction of regional power, and the dynamic bal ance of regional interest. The basic elements cover essential elements and form elements. The former in cludes the supremacy of law, the coordination of law, reason, and sensibility, overall and responsible gov ernment, civil subject,and the shared governance of regional society. The latter includes coordinate legis lation,coordinate reinforcement of law, authoritative regional judicial mechanism and multiple regional conciliation mechanism.
