Quantifying the Impact of Public–Private Partnerships on Economic Development: A European-Level Analysis

This study investigates the relationship between public–private partnerships (PPPs) and local economic development across European countries using a quantitative, multivariate regression approach. Focusing on the total value of capital invested and the number of PPP projects, the analysis draws on official Eurostat and PPP database data for 2012–2024. Results show that the number of PPP projects is the strongest determinant of capital mobilization, highlighting the importance of implementation intensity and institutional capacity in attracting private investment. Other macroeconomic variables, such as GDP per capita growth, unemployment, investment share, and labor quality, exhibit weak individual effects but contribute to the model’s overall explanatory power. Residual analysis indicates the influence of country-specific institutional and governance factors. The findings underscore the value of PPPs as instruments for fostering investment and local development, providing empirical evidence to guide policymakers in designing effective frameworks that enhance PPP efficiency and outcomes.
