The Visiting Scholars Program was created in 2009 by Professor Yan Song in an effort to foster collaborative international research concerning the problems faced by Chinese cities. Visiting scholars come from all over China, and include professors and doctoral students. They typically come to UNC-Chapel Hill for a period of six months or a year. Their work focuses on a variety of areas, including sustainable environment and energy; land use and transportation planning; urban redevelopment and its social equity implications; economic development policy; property rights, infrastructure planning and government finance. Since its creation, PCC has hosted more than 170 visiting scholars from China.
