1. If your enterprise often applies for projects, you should know people from relevant departments and visit/consult;
2. If your enterprise has never declared a project, you'd better find an agency to help you declare it, or when consulting the government department, the government department will have an agency that often cooperates. You can ask.
3. Go to official website of National Development and Reform Commission to inquire about the project notice, management method and process. According to the contents of the notice, you can call the department you want to declare. Under normal circumstances, teachers who are consulted are more patient.
I hope you can understand the project application information in many ways, so that you can have a good idea whether you declare it yourself or as an agent. I hope I can help you.
