Abstract:Taking one season paddy rice in Hubei Province as research object,the life cycle assessment method was adopted to quantify the relevant environmental impacts within the rice production boundary,and the superefficient SBM model was applied to measure the ecoecological efficiency of farmers. On this basis,Tobit and OLS models are used to analyse the effects of green cognition and environmental regulations on agricultural ecoefficiency. The results showed that aggregate life cycle environmental impact index of rice paddy system was 2.099. The average ecoefficiency of rice was 0.64. More specifically,the proportion of farmers in low efficiency group,in middle efficiency group and in high efficiency group was 81.08%,4.86%,14.05%,with an average value of 0.55,0.85 and 1.11,respectively. Both the green cognition and the government regulation had a significant positive impact on rice ecoefficiency. Among the economic,resource and market conditions determinants of ecoefficiency,per capita assets and per capita capital investment had a positive influence on ecoefficiency; both machinery use intensity and irrigation had a negative influence on ecoefficiency,while sown area and per household labor capacity had a positive influence on ecoefficiency; and the rice commercialization rate had a negative influence on ecoefficiency. Based on those findings,we recommend expanding the number of farmers with high ecoefficiency,enhancing farmers’ sense of responsibility for improving environmental quality,strengthening on the promotion of agriculture green production knowledge,and enforcing support of farmers’ economic conditions,resource conditions and improving market construction of green agricultural products to realize the green transformation of agricultural production mode.
