Spatiotemporal Evolution and Spatial Convergence Analysis of Total Factor Productivity of Citrus in China

In this study, the DEA–Malmquist index method was used to measure total factor productivity of citrus in seven major mandarin-producing provinces and tangerine-producing China from 2006 2020. Moran’s I test spatial correlation mandarin tangerine, its σ convergence β characteristics were explored using coefficient variation panel models. The results show that perspective time series evolution, growth rate tangerine slowed down year by after reaching maximum value 2008. Technological progress main affecting citrus. more stable than mandarin, pure technical efficiency scale change not stable. From regional differences, China’s citrus-producing all indicated positive growth, showing an increasing trend east west. drivers mainly technological efficiency. differences for obvious tangerine. showed characteristics; spillover effect significant; there convergence, absolute conditional convergence. Regional disparities industry development can be objectively reflected analysis takes factors, economic social other factors into account.
