Analysis on the Effect of Different Industrial Organization Models on Technical Efficiency of Maize Production——Empirical Analysis Based on the Data from 904 Farm Households in Heilongjiang Province
Using 904 farm households data from the 2019 Rural Economic and Social Situation Household Sur-vey in Heilongjiang Province,the data envelopment analysis method and the propensity score matching method were selected to estimate the effects of different industrial organization models on the technical efficiency of maize pro-duction under the integration of maize production and processing.The results showed that,the average of production technical efficiency of overall maize production and processing in Heilongjiang Province was 0.874,signifying a rela-tively high level of production technology efficiency.The industrial organization model formed by the integration of maize production and processing could improve the production technical efficiency of farmers,but there was vari-ability in the enhancement effect of different industrial organization models,and the vertical integration model had the highest degree of impact on the technical efficiency of maize production,with a net effect of 0.021 9,followed by the production contract model,which is higher than the order contract model.Additionally,factors such as house-hold head characteristics,family business characteristics,land characteristics and environmental characteristics al-so have an impact on the improvement of technical efficiency of maize production.
