This study examines how selected knowledge-economy pillars (tertiary enrollment, Internet use, resident patent applications, and scientific and technical articles) relate to the Human Development Index (HDI) in eight Arab countries over 2010–2022, controlling for GDP per capita. Data come from the World Bank’s World Development Indicators and the UNDP Human Development Reports. The analysis relies on second-generation panel techniques, namely the Pesaran CD test, the Pesaran–Yamagata slope homogeneity test, the CIPS unit root test, and the Westerlund cointegration test, with relationships estimated through the Common Correlated Effects Mean Group (CCEMG) and Augmented Mean Group (AMG) estimators, which account for the cross-sectional dependence and slope heterogeneity detected. Because the Westerlund test does not confirm cointegration, coefficients are interpreted as average associations, not long-run effects. Under CCEMG, tertiary enrollment, Internet use, and GDP per capita are positively and significantly associated with the HDI, whereas scientific articles and patents are not; AMG largely supports these results, with scientific articles weakly significant at the 10% level. These findings highlight education, digital connectivity, and economic prosperity as more closely linked to human development than formal scientific and innovation output. The study contributes by examining the pillars separately within a single econometric framework for the Arab context, though it is limited by sample size, period, and data availability. Keywords: knowledge economy; human development; Human Development Index; Arab countries; panel data; CCEMG Introduction In recent decades, economic and social growth has been seen as an essential starting point for human development, whose notion has moved from productivity and wealth toward extending human capacities, choices and opportunities. The Human Development Index (HDI), a widely used indicator for comparing countries, combines three dimensions: a long and healthy life, access to knowledge and a reasonable standard of living. Human development thus depends not only on economic resources but also on a society’s ability to develop human talents and provide opportunities to learn from knowledge. Amid rapid economic and technological transformations, the creation, diffusion and use of knowledge have become crucial to nations’ economic and social capacities. Education, research, innovation, digital communication and access to information are interrelated in contemporary knowledge systems, as the multidimensional Global Knowledge Index reflects (United Nations Development Programme, & Mohammed bin Rashid Al Maktoum Knowledge Foundation, 2025). The indicators selected here are not exhaustive of the knowledge economy but are pillars consistent with the study’s purpose that can be monitored consistently across nations and over the study period. Each pillar represents a stage in the knowledge process, beginning with human capital. Higher education builds specialised abilities, supports research and innovation, and strengthens the capacity to acquire and use information; the gross enrolment ratio in higher education is therefore an operational measure of one component of human capital development, not a synonym for education or human capital per se. Building on these skills, information and communication technologies determine how widely knowledge can be accessed. Internet use is a quantitative proxy for the digital environment and may relate to human development by promoting access to educational material, health services and economic possibilities, though this relationship varies with the level of development and the type of technology(Bala, 2024) . Knowledge also involves generating new knowledge and transforming it into applications and inventions. Resident patent applications measure inventive output, and scientific and technical articles measure the production and dissemination of scientific knowledge; yet patent counts do not always reflect quality or economic and social worth, nor publication counts research quality or developmental impact. The indicators remain relevant despite these limits, particularly given the significant variations between Arab nations in education, internet connectivity, scientific research and innovation. The Global Knowledge Index emphasises continuing gaps in education, research and development, innovation and digital infrastructure (United Nations Development Programme, & Mohammed bin Rashid Al Maktoum Knowledge Foundation, 2025), making the links between these capacities and human development outcomes an important research issue in the Arab area. Rapid digital developments also raise the question of whether digital and knowledge infrastructure can turn technical advances into tangible opportunities. The World Human Development Report stresses that technology is not an end in itself; its developmental worth lies in expanding human capacities and choices(United Nations Development Programme, 2025) . Studying human development in the Arab context therefore requires moving beyond income and growth to directly measurable components of the knowledge system. The study focuses on four interconnected yet distinct indicators: higher-education enrolment (human capital formation); the percentage of internet users (digital penetration and access to knowledge); resident patent applications (technological innovation output); and scientific and technical articles (scientific knowledge production). The central problem is to examine how far these pillars are linked to human development in Arab countries, and whether the relationships persist after controlling for income. The study tests the relationship between the four indicators and the HDI for a sample of Arab countries during 2010–2022, with per capita GDP as a control variable. The study starts from the premise that disparities in human development among Arab countries may be partly linked to differences in capacity to build human capital, expand digital access to knowledge, produce technological innovations and generate scientific knowledge. It therefore breaks the
