Abstract: Using the panel threshold model proposed by Hansen, this paper empirically studies the nonlinear relationship between agricultural labor productivity and rural residents’ income gap based on panel data of 29 provincial units from 2000 to 2014. The results show that there are distinctive relations between agricultural labor productivity and rural residents’ income gap divided by thresholds rather than a single linear relationship. In different ranges of thresholds, the influence of agricultural labor productivity on rural residents’ income gap is different. When the agricultural labor productivity is less than per capita 4 372.19 Yuan, the improvement of agricultural labor productivity can effectively narrow the income gap of rural residents; when the agricultural labor productivity cuts across the first threshold of per capita 4 372.19 Yuan, its improvement has little effect on the income gap of rural residents; when it leaps over the second threshold of per capita 6 023.46 Yuan (i.e. the inflection point), its improvement will widen the income gap of rural residents. Currently, the agricultural labor productivity in China has crossed the second threshold, so the expansion of rural residents’ income gap should be concerned by all parties.

Key words: agricultural labor productivity, panel threshold model, rural residents' income gap
