Research on the Effects of Agricultural Technology Investment on Farmers' Income Structure

摘要

The effect of agricultural technology investment on famers' income structure has been ignored for a long time. Based on the 1989-2012 time series data, this paper uses VAR (p) model, dynamic co-integration analysis and impulse response function to analyze the relationship between agricultural technology investment and famers' income structure. Empirical results show that, the effect of agricultural technology investment on farmers' income structure is significant. The agricultural R&D expenditure has positive effects on famers' functional distribution and scale distribution of income, while agricultural technology promotion expense has negative effects. In comparison, the impact of the former is larger than the latter.
