This report focuses on the multiple barrier-free needs of people with disabilities by improving the barrier-free environment construction level of buildings，under the process of modernization of national governance system and governance capacity. This report analyzes the historical evolution，current characteristics，main problems and legislative suggestions of barrier-free construction of buildings in China. The barrier-free environment of buildings in China has experienced two practical stages：the initial stage of reform and opening up and rapid urbanization period. It is in the stage of high-quality development that the welfare model oriented legal system shows difficulty in adapting to the diversified and systematic barrier-free needs of people with disabilities and the fuzzy legal responsibility have become the main problems hindering its further improvement. Based on this，this report suggests that we should establish a barrier-free legislative system for everyone at the legal level，optimize and improve relevant industry norms to meet the diversified barrier-free needs of the people，and create a jointly environment with the sharing responsibilities and obligations of different stakeholders in maintaining the construction of barrier-free environment. Therefore，our goal is to build a barrier-free governance environment and system with clear division between the central government and the local government through the path of cooperation between government，market and all citizens.
