国家统计局数据显示，1月份至8月份，我国民间固定资产投资同比下降2.3％，降幅较前7个月有所扩 大。尽管整体数据承压，民间投资结构却变化积极，韧性较强。接下来，要进一步聚焦效益、精准发 力，通过拓展有效投资空间，推动我国民间投资持续回暖和结构优化。 此前出台的《关于进一步抓好抓实促进民间投资工作努力调动民间投资积极性的通知》，从明确工作目 标、聚焦重点领域、健全保障机制、营造良好环境4个方面，提出17项具体措施，涵盖项目推介、要素 保障、问题反映和工作考核等创新举措。今年5月20日起实施的《中华人民共和国民营经济促进法》， 专设"投资融资促进"章节，立法保障"支持民营经济组织参与国家重大战略和重大工程""支持民营经济 组织参与政府和社会资本合作项目"。这为民间投资营造了良好的政策环境，增强了民营企业投资信 心。 有效化解"不愿投"难题，拓宽民间投资回报空间。进一步放开民间投资市场准入，在基础设施、公共服 务、战略性新兴产业等领域推出一批优质项目，支持民间资本平等参与竞争。完善投资激励机制，对民 间投资参与的重点项目给予适当的财税支持和要素保障倾斜。创新投资模式，推广政府和社会资本合作 （PPP）模式，规范合作 ...

Core Viewpoint - The article discusses the complexities and challenges in the financing and debt repayment mechanisms of cross-regional infrastructure projects in China, particularly focusing on the use of Public-Private Partnership (PPP) models and special bonds. Group 1: Project Funding and Debt Responsibility Complexity - Cross-regional infrastructure projects, especially in railways and highways, have complex funding structures involving local government fiscal funds, bank loans, and social capital. The debt and funding responsibilities are not always directly correlated [2]. - Local governments often incur debt corresponding to their funding responsibilities in projects, leading to fragmented debt representation across multiple sub-projects, particularly in PPP projects [2]. Group 2: Special Bonds and Debt Repayment Sources - Recent changes allow PPP projects to utilize special bond funds, which are linked to government funding responsibilities rather than direct project revenues. This indicates that government borrowing is influenced more by social benefits than by project profitability [3]. - In projects like toll roads and railways, the repayment of special bonds may not rely on operational income, leading to a significant asymmetry between project profitability and debt repayment sources [4]. Group 3: Measures and Practical Operations - Local governments and project companies are implementing measures to ensure the repayment of special bonds, such as requiring project companies to agree that revenues can be used for debt repayment [7]. - In cases where operational income is insufficient, local governments may resort to land transfer revenues as a repayment source, particularly in regions with active real estate development [7]. - Additional projects and revenue sources, such as advertising and parking fees along railway lines, are being considered to supplement income for special bond repayment [7]. Group 4: Conclusion - The financing and debt repayment mechanisms for cross-regional infrastructure projects face multiple challenges, particularly in the design of debt responsibilities and repayment sources in PPP projects. Factors like project profitability, shareholder dividend decisions, and local government fiscal burdens significantly impact the repayment of special bonds [6]. - With ongoing policy improvements and the application of special bonds in PPP projects, the future financing models for infrastructure are expected to become more diversified and flexible, supporting sustainable economic development in China [6].
