Briefly describe the constraints on the maximum size of an investment project.

Answer: the main factors affecting the construction scale of investment projects:

1. The country's economic plan and development planning. Different types of projects have different planning requirements, planning requirements for centralized production and construction of the project, the scale can be larger, and vice versa, smaller; in addition to national key or backbone project construction scale should be considered in accordance with the country's medium- and long-term plan, the general construction projects are based on sectoral and regional planning to consider.

2. Market gap. That is, the difference between market demand and market supply, the gap between the project, the scale can be larger, and vice versa, smaller, but the construction scale of the project can not be larger than the predicted market gap.

3. Production of capital preservation scale. This is to make the cost of the project and the benefits of equal size, that is to say, the minimum size of the enterprise can not be lower than the capital preservation scale, otherwise the enterprise will be unprofitable.

4. The technical characteristics of the project industry. Different industries require different construction scale, to consider the constraints of the technical characteristics of the industry, such as the size of the mining industry must take into account the storage capacity of the mine and geological conditions, hydroelectric power plants must consider the flow of water sources.

5. Product characteristics of the project. Generally speaking, the scale of the product is simple, few varieties, the market demand for large projects, the scale should be mainly large, and vice versa to small and medium-sized.

6. Production conditions and availability of funds. Here is actually talking about the supply of resources, that is, material resources and the adequacy of financial resources, the former test is whether the enterprise has sufficient raw materials, energy, transportation and other production conditions, the latter test is the enterprise's ability to finance and the maturity of the national financial market.
