Conception is the premise to recognize things and to think logically. The conception of environmental administrative public proceedings is chaotic in the academic world, and the main divergence lies in the recognition of subject element and object element about the conception. In order to accurately define the conception, citizens, individuals, corporations, organizations, the abstract and concrete administrative act should be discriminated. Based on seeking common ground, environmental administrative public proceedings should be defined as the proceeding for the purpose of public interest filed by statutory bodies, enterprises or individuals who have no interest in legal claiming for violation or failing to comply with the statutory duties that cause environmental pollution and ecological destruction to the people’s court. It remains essentially administrative proceedings.
