概要	An e-government maturity model is a staged framework that describes how public administrations evolve their digital service delivery from simple online information toward fully integrated, transaction-capable government. The most influential formulation, proposed by Karen Layne and Jungwoo Lee in 2001, sets out four stages — cataloguing, transaction, vertical integration and horizontal integration — through which agencies are expected to progress. Maturity models translate a diffuse modernisation agenda into an ordered ladder of capabilities that can be assessed, compared and benchmarked across agencies and countries. They underpin international instruments such as the UN E-Government Survey and its Online Service Index.	The Worldwide Governance Indicators (WGI) are a long-running World Bank project that measures the quality of governance across more than two hundred countries on six dimensions: voice and accountability, political stability and absence of violence, government effectiveness, regulatory quality, rule of law, and control of corruption. Developed by Daniel Kaufmann, Aart Kraay and Massimo Mastruzzi from 1999, the WGI combine hundreds of underlying variables from dozens of survey and expert sources using a statistical unobserved-components model. The result is a set of comparable scores, each accompanied by an explicit margin of error, published on the World Bank's governance portal.
