Abstract:The amount of comprehensive development projects in regional areas is huge. The Chinese government is increasingly paying attention to the hidden debts of local governments. It is difficult to carry out the high-quality construction and reconstruction of large areas solely relying on the government financial funds. Based on the characteristics of the investor + EPC + operation model, the applicability of this model in the three stages of comprehensive development in the area is analyzed. In the investor + EPC + operation mode, the contractors can usually solve the project construction funding issues in the early stage of project construction, efficiently complete the project construction in the medium term, and provide the urban operation services in the later stage, and assist in the industry introduction to promote the high-quality development of regional construction.
