Professor Yi’s teaching and research interests are focused on public policy theories broadly, and energy policy and governance specifically. His research covers areas of energy policy, environmental policy and economic development. In the area of energy policy, he evaluates the employment impacts of state and local energy policies in the U.S. metropolitan areas. He also investigates the interaction patterns among policy tools for renewable energy at the state level.


He is also interested in recycling and solid waste management, especially the impact of policy designs on recycling performance in the cities and counties.

In addition to policy analysis, he conducts theoretical work to uncover the sources of policy change in the energy policy arena, through studying the formation mechanisms underlying the organizational network among government agencies, energy businesses and environmental NGOs, as well as citizens.


Professor Yi earned his doctorate in Public Administration and Policy from Askew School of Public Administration and Policy at Florida State University in August, 2012.

Professor Hongtao Yi has an article titled “Green economy in China: Regional variations and policy drivers” published in the peer-reviewed journal Global Environmental Change. In this study, Yi and his coauthor Yuan Liu, a Glenn school MPA graduate, measure clean energy economy at the city level in China, by counting green jobs and firms through an analytical approach. Spatial error model (SEM) analyses indicate that local clean energy policies, along with socio-economic factors, explain the variation in green economy across cities. This paper provides preliminary findings to compare green economy in China and United States. » Click here to read the paper.

Professor Hongtao Yi has an article titled “Green businesses in a clean energy economy: Analyzing drivers of green business growth in U.S. states” in the peer-reviewed journal Energy. The paper looks at the factors driving the growth and survival of green businesses in the United States. Analysis reveals that the adoption of renewable energy policies, the permission of renewable energy credits imports, the stringency of minimum wage legislations, and presence of clean energy business associations are the major driving forces of the green business development in the U.S.. » Click here to read the article

Professor Hongtao Yi’s research was recently published in Energy Policy. The article is entitled “Clean energy policies and green jobs: An evaluation of green jobs in U.S. metropolitan areas”. Yi’s paper investigates whether existing state and local climate and clean energy policies have influenced the distributional patterns of green jobs in U.S. metropolitan areas using employment data in 2006. The empirical results suggest that both state clean energy policy tools and local climate actions have moderate and positive effects on the number of green jobs. »Click here to read the paper
