Generally speaking, the approval of the project proposal is one of the important basis for the feasibility study report; the feasibility study report is one of the follow-up documents of the project proposal. In addition, during the feasibility study stage, the project must at least have a conceptual design, and professional consulting opinions on municipal administration, transportation and environment are also essential. For real estate projects, approval of detailed regulations or construction detailed regulations is generally required. The investment estimation requirements at this stage are relatively detailed, with an error of ±10 in principle; accordingly, the financing plan must also be detailed, and the annual construction investment must be implemented. Projects with bank loans must have credit certificates issued by the bank. When many projects are applied for project approval, the conditions are relatively mature, and land, planning, environmental impact assessment, professional consulting opinions, etc. are basically in place. In particular, the source of project funds is entirely self-raised by the project legal person, with no financial funds and no special policies.
