Abstract:

New regionalism provides an analytic frame for the co-governance of trans-boundary pollution，concerning issues of “who，what，how” and the performance of the co-governance.From the perspective of the new regionalism，we hold that the subject co-governing trans-boundary environmental pollution is multiple，and the main object of governance is trans-boundary water pollution and atmosphere pollution.It is suggested that co-governance model and network should be established，and the governance performance should include economic performance，social performance，ecological performance，and comprehensive performance.

Key words: trans-boundary environmental pollution area, co-governance, new regionalism, institution
