Regulatory Quality: Percentile Rank, Upper Bound of 90% Confidence Interval

Good governance is essential for development. It helps countries improve economic growth, build human capital, and strengthen social cohesion. Empirical evidence shows a strong causal relationship between better governance and better development outcomes. The Worldwide Governance Indicators (WGI) are designed to help researchers and analysts assess broad patterns in perceptions of governance across countries and over time. The WGI cover over 200 countries and territories, measuring six dimensions of governance starting in 1996: Voice and Accountability, Political Stability and Absence of Violence/Terrorism, Government Effectiveness, Regulatory Quality, Rule of Law, and Control of Corruption. The aggregate indicators are based on several hundred individual underlying variables, taken from a wide variety of existing data sources. The data reflect the views on governance of survey respondents and public, private, and NGO sector experts worldwide

Regulatory Quality captures perceptions of the ability of the government to formulate and implement sound policies and regulations that permit and promote private sector development.

Percentile rank indicates the country's rank among all countries covered by the aggregate indicator, with 0 corresponding to lowest rank, and 100 to highest rank. Percentile ranks have been adjusted to correct for changes over time in the composition of the countries covered by the WGI.

Percentile Rank Upper refers to upper bound of 90 percent confidence interval for governance, expressed in percentile rank terms.

良治（Good governance）对于发展至关重要。其可助力各国提升经济增长水平、培育人力资本，并强化社会凝聚力。实证研究表明，治理水平提升与发展成果优化之间存在显著的因果关联。
全球治理指标（Worldwide Governance Indicators，WGI）旨在为研究人员与分析人士提供评估各国及不同时期治理认知整体格局的工具。该指标覆盖超过200个国家与地区，自1996年起涵盖六大治理维度：话语权与问责制（Voice and Accountability）、政治稳定性与无暴力/恐怖主义（Political Stability and Absence of Violence/Terrorism）、政府效能（Government Effectiveness）、监管质量（Regulatory Quality）、法治（Rule of Law）以及腐败控制（Control of Corruption）。综合指标基于数百项独立的底层变量，这些变量取自各类现有数据源，反映了全球范围内受访者、公共及私营部门人士与非政府组织（NGO）专家对治理状况的评价。
监管质量（Regulatory Quality）旨在衡量各国政府制定并实施健全政策与监管框架，以允许并促进私营部门发展的能力感知。
百分位排名代表该国在综合指标覆盖的所有国家中的位次，0对应最低位次，100对应最高位次。百分位排名已针对全球治理指标覆盖国家构成随时间产生的变化进行了调整。
百分位排名上限（Percentile Rank Upper）指以百分位排名形式呈现的治理状况90%置信区间的上限值。
