This study examines whether convergence in institutional quality distinguished by economic and political dimensions of institutions has occurred across countries. The study uses data from 81 countries over the period of 1985 to 2018. The study tests the convergence hypothesis by using three different measures of institutional quality capturing political and economic dimensions of institutions. The empirical results show that convergence in economic institutional quality has occurred and most countries with weak economic institutions have a higher rate of change compared with countries with strong economic institutions. In contrast, for political institutions, the convergence process is short-lived.

经济改革与政治停滞：制度变迁的不一致模式

本研究考察了以制度的经济和政治维度区分的制度质量是否在各国发生了趋同。该研究使用了 1985 年至 2018 年期间来自 81 个国家的数据。该研究通过使用三种不同的制度质量衡量指标来捕捉制度的政治和经济维度来检验收敛假设。实证结果表明，经济制度质量出现了趋同，大多数经济制度薄弱的国家与经济制度强的国家相比，变化率更高。相比之下，对于政治制度而言，趋同过程是短暂的。
