Regional difference of farmers' investment willingness in small-scale irrigation and its influencing factors: Based on 471 households questionnaires at major and non-major grain producing areas in Hunan

Based on 471 households' survey data at major and non-major grain producing areas in Hunan, establishing Multiple Logistic model with 14 independent variables from 4 groups, this paper made a regional comparative analysis of farmers' investment willingness in small irrigation and water conservancy construction and its influencing factors. The results showed that: In general, most farmers were willing to invest small irrigation and water conservancy construction, but the farmers' willingness in major grain producing areas was greater than that of non-major areas. Farmers' investment willingness in both major and non-major grain producing areas was influenced positively by education level, health condition, grain income, grain subsidies, natural disasters, and so on. but farmers' evaluation of the current overall condition of farmland water conservancy facilities had negative impact on investment willingness. Family labor shortages had significant negative or positive effects at different areas. Irrigation methods, number of medium-sized water conservancy construction had no significantly effect on the farmers 'investment willingness in major grain producing areas, but showed a significant positive impact on farmers at non-major areas. Conversely, the expected future investment plan had a significant positive impact on the farmers' investment willingness at major grain producing areas, while showed no significant effect on farmers at non-major grain producing areas.
