Abstract: Cleaner production is an effective measure in environmental governance and an important aspect of the collaborative development in Beijing,Tianjin,andHebei.It is necessary to provide a favorable system to guarantee the collaborative legislation of cleaner production in these three regions.Due to the differences in economic development,scientific innovation and orientation of local development,the legal documents of cleaner production also differ in their effectiveness and contents in these three regions.Considering the constraints and relevant legalization and policy foundations,we think that the collaborative legalization should follow a principle of unified standard and procedure to cover the three major industries,collaboratively designing coordination mechanism,special funds,system of scientific and technological innovation and information sharing platforms for the competent departments.By doing so,we can provide clear legal basis and system safeguard for the coordinated development of cleaner production,for the improvement of environmental governance,and for the synchronic upgrading of industrial structures in these three regions.

Key words: Beijing,Tianjin and Hebei, the collaborative development；cleaner production, collaborative legislation
