PPP项目伙伴主体、合作环境与公共产品供给的关系研究--基于结构方程模型的分析

摘要

With the structural equation model,this paper studies partners,cooperative environment, and public products supply of PPP proj ects and their interrelationship.A number of empirical findings are revealed.First,the cooperative environment,partners,and public involvement exert a considera-ble influence on the supply of public products;second,a favorable cooperative environment and be-nign public involvement contribute to the sustainability of PPP partnership and proj ect supply;third, the policy advantages and resources of the public sector are the prerequisite for maintaining the part-nership.It is argued that partnership is based on the balanced mutual dependence,which is established in organizations'exchanging resources.The government can promote the effective supply of public products and strengthen the quality of partnership by enhancing the construction of cooperative envi-ronment and raising public involvement.%运用结构方程建模的方法对我国城市基础设施 PPP 项目伙伴主体、公众参与、合作环境以及公共产品供给的相互关系进行实证研究。研究表明：伙伴主体、合作环境和公众参与对公共产品供给具有重要影响；良好的合作环境和公众参与，将促进PPP 伙伴主体及 PPP 项目供给的可持续；公共部门的政策优势与资源禀赋是PPP伙伴关系维系的必要条件。PPP伙伴关系是组织间交换资源形成平衡的依赖关系，政府加强合作环境建设与引导公众参与必然推进公共产品有效供给，从而提升PPP伙伴主体之间合作的关系质量。
