The purpose of this study is to find principal factors affecting CZER (China Zero Environmental Risk) from behavior angle, and compare the above factors between different periods, and the related advice can help people to solve environmental problems. So in this study the factors’ selection, contribution and sequence by correlation, regression, principal component analysis, and comparison of the above factors between different periods, etc. were studied from behavior angle, which is different from the present work only studying individual behavior. Especially in this study, emphasis was put on comparison of principal factors affecting CZER between different periods from behavior angle. To make sure this study applicable, data were collected by case study, and such norms as KMO (KMO refers to Kaiser-Meyer-Olkin Measure of Sampling Adequacy), etc. were abided by. By this study, on one hand, there are such aspects in common as production action, living action, production waste disposal, living waste disposal, public management, and market management. On the other hand, they are different in such aspects as natural cause only for CZER during Period 2, and factors have different sequence by contribution for different periods. And the related advice is as follows: first, careful protection of natural environment. Secondly strict surveillance on production of waste from such behaviors as enterprise production and human living action by market management, and public management, etc.. And thirdly great encouragement to arouse interest in technological innovations friendly with the environment in waste disposal, etc..
