北京基础设施投资力度持续加大，交通道路、污水处理、能源生产等领域建设能力不断提升，但首都人口密度过大，基础设施承载压力大，地铁覆盖面不够，污水处理缺口大，环境污染严重等“城市病”需要系统性治理。应以京津冀协同发展为战略指导，加强首都城市圈基础设施均衡化、一体化建设与发展，加大轨道交通设施建设密度和覆盖面，构建首都水生态圈，开发低碳新能源，鼓励社会资本参与周边区域基础设施投资与建设，为疏解非核心功能和产业转移、人口外迁提供重要保障。
To further implement the capital city of strategic positioning，and strengthen the capital city disease treatment，we need to accelerate the pace of infrastructure construction in Beijing. Beijing infrastructure investment increased continuously，and continuously improve of building capacity as the traffic roads，sewage treatment，energy production and other fields. But in Beijing，the city need systematic governance for excessive population density，infrastructure bearing pressure，Metro coverage is not enough，the big gap of sewage treatment，serious environmental pollution and other disease problems. To strengthen Beijing megalopolis disease governance，we need to the strategic guidance of Beijing-Tianjin-Hebei Cooperative Development，strengthen the construction and development of the infrastructure equalization，integration in the capital city circle，increasing rail infrastructure construction density and coverage，constructing the capital water ecosystem，and the development of low carbon new energy，to encourage social capital to participate in infrastructure investment and the surrounding area construction，to solve the noncore function and the transfer of industries，population relocation provided an important guarantee.
