A bibliometric review of urban energy metabolism: Evolutionary trends and the application of network analytical methods

Urban energy metabolism reflects the transmission and exchange process to uncover structure functionality of urban activities. The literature on is overwhelming still growing. However, few publications have attempted provide a specific review metabolism. Therefore, this study conducted systematic bibliometric analysis explore research status emerging trends. Results showed that amount co-cited displayed an upward trend during period. After 2006, number implied upsurge. Based co-word keywords, “energy” occupied much attention research. high citation keywords relating network analytical methods in were analyzed via network, including ecological analysis, input-output complex network. combination has been widely applied studies worldwide, especially context China. Consequently, future opportunities suggested from following aspects: (1) inclusion both spatial temporal dimensions metabolic systems, (2) ability unravel interactions components dynamic manner. findings not only beneficial for scholars detail holistic picture current progress, remained questions methods, but also valuable assist practitioners evaluate monitor performance with suitable methods.
