Who does it better and why? Empirical analysis of public-private partnership in infrastructure in Asia-Pacific

PurposeThis research has two primary goals: first, to develop a composite index that evaluates the degree to which Asian–Pacific economies are prepared to engage in public–private partnerships (PPPs), and second, to investigate the factors that have been most influential in the formation of PPP arrangements in the nations' infrastructure over the course of the period 1995–2016.Design/methodology/approachThe study constructs sectoral and overall index of possible determinants of PPP. Subsequently, it examines each constructed index's role in PPP investment. The author also conducted a panel data analysis to understand the role of each of the potential determinants on PPP projects and investments. This paper analyzes the author’s empirical models using a range of cross-section and panel estimators, including Poisson, zero-inflated Poisson and fixed effect.FindingsThe study’s results based on cross-section analysis suggest that regulatory and institution quality, institutional arrangement and regulatory frameworks, financial market development and macroeconomic stability positively impact investment in PPP. Moreover, the results depict that financial market development has the most substantial impact on PPP investment, followed by macroeconomic stability and prior experience with PPPs. The panel data analysis shows that per-capita income, financial development, inflation, debt, resource import and fuel export are crucial determinants of PPP in Asian–Pacific economies.Practical implicationsGovernments of the countries should promptly amend the important policies outlined in this study and adopt a more robust strategy to foster a competitive PPP environment. This will aid in maintaining transparency and gaining the confidence of investors. The study’s findings may assist policymakers in focusing on specific areas in need of improvement. Social welfare and industrialization are ultimately enhanced by the formulation of such policies and by attracting additional infrastructure investment.Originality/valueThis is the first attempt to rank countries on the basis of PPP enablers. Unlike previous studies, this study examines the role of a large number of indicators in determining PPP investment and projects in cross-section as well as panel data framework. The study also investigates the effects of PPP specific provisions and rules. Furthermore, the focus is specifically on Asian–Pacific countries, which are a mix of third-world, emerging, developing and developed countries. Focusing on Asia–Pacific is also crucial because the region is home to most of the world's population, and the region's infrastructure outcomes significantly impact their lives.
