A time differencing qualitative comparative analysis (QCA) of public-private partnership (PPP) market maturity
研究制度变迁如何影响公私合作伙伴关系市场成熟度，使用时间差分定性比较分析法分析了2009-2014年间19个拉美和加勒比市场，发现完善监管框架和制度知识是提升成熟度的必要条件，而投资环境恶化与监管弱化则导致成熟度下降。
This study examines how institutional change affects public-private partnership (PPP) market maturity. Using a novel Time Differencing Qualitative Comparative Analysis (QCA) method, the institutional settings of 19 different PPP markets across Latin America and the Caribbean (LAC) were analysed between 2009 and 2014. The results show enhancing the regulatory framework and institutional knowledge are necessary in order to increase PPP market maturity in most cases. However, a deteriorating investment climate coupled with a weaker regulatory framework led to declines in PPP market maturity. This suggests that the influence of institutional change on PPP market maturity is not symmetrical.
