The sources of total factor productivity growth in Chinese agriculture: technological progress or efficiency gain?
Provincial panel data from the agricultural sector and stochastic frontier production function model were employed to study the total factor productivity (TFP) growth since the 1980s in China. We decomposed the TFP growth into technological progress and technical efficiency changes (efficiency gains) as well as the aggregate agricultural TFP growth into crop-specific subsector's TFP growths. We found that Chinese agriculture experienced significant productivity growth in the last few decades, although the growth rates vary considerably among the subsectors. During this period, the source of productivity growth comes from either technological progress or efficiency gains, not from both of them simultaneously. Particularly since the 1990s, Chinese agriculture experienced a great technological progress and yet a considerable efficiency loss. The differences among sources of productivity growth and among subsectors call for distinct policy responses.
