我国正处于转轨时期,私营企业在对我国GDP的贡献度,提供劳动就业岗位,科技创新领域,创税方面都起到了重要作用。但是由于法律法规不健全,规模不经济,信息不对称,市场不完备等原因,私营企业面临融资难的问题。PPP模式可以使公共部门和私营企业共同参与公共基础设施的建设和运营,既为社会和公众提供服务,又为私营企业开辟了融资的新途径。 China is in a period of transition. Private-owned enterprises play an important role in contributing to China’s GDP, providing jobs in the fields of employment, scientific and technological innovation, and establishing a tax system. However, due to the imperfect laws and regulations, uneconomical scale, asymmetric information and imperfect market, private enterprises are facing the problem of financing difficulties. The PPP model allows the public sector and the private sector to participate in the construction and operation of public infrastructure, both as a service to society and the public, and as a new way of financing private industry.
