Study On The Influence Of Crop Planting Structure On Agricultural Mechanization Level

Agricultural mechanization is one of the important signs to promote the development of agricultural modernization in a country.From the current development situation in China and the analysis of existing research theories,agricultural mechanization plays an important role in the development of modern agriculture.Therefore,the key influencing factors of agricultural mechanization in China are analyzed.The study of agricultural mechanization promotion mechanism is of great significance for the development of agricultural mechanization in China.This study used 363 county-level microdata from Hubei Province to investigate the data of three time points in 2005,2010,and 2016,and used a fixed effect model to analyze the impact of planting structure on the level of agricultural mechanization.The empirical results show that the planting structure has a significant positive impact on the level of agricultural mechanization,ie,the more uniform the planting structure,the higher the Hilfindal index(HHI),the higher the level of agricultural mechanization;the introduced control variable,cultivated area,age,The ratio of rice and non-agricultural income has a significant positive impact on the level of agricultural mechanization;the proportion of maize and labor in the control variables have a negative effect on the level of agricultural mechanization,but this is not significant.In addition,this study is based on 31 provincial macroscopic panel data from 2005 to 2014,using fixed-effect model and differential GMM model to conduct regression analysis on the relevant factors affecting the level of China's agricultural mechanization.The focus of this study is on the planting structure of agricultural mechanization.The level of influence.The research results show that crop planting structure has a significant impact on the level of agricultural mechanization.Among them,the Hilfindal index(HHI value)and industry concentration(CR4)have a positive effect on the level of agricultural mechanization.The urban registered unemployment rate,per capita net income of farmers,and the ratio of industrial GDP to total GDP have a significant positive impact on the level of agricultural mechanization;the total sown area of crops in each province and city has a significant negative impact on the level of agricultural mechanization;rural electricity consumption,agriculture The proportion of population has no significant effect on the level of agricultural mechanization.Finally,policy recommendations are given:first,develop suitable local crops according to local conditions;second,establish land transfer platforms and strengthen centralized management of land;third,accelerate the construction of transport infrastructure and improve market information;fourth,help adjust the cropping structure and promote agriculture.Machinery will "strengthen" on the supply side.Fifth,it will adjust the planting structure and give full play to the planting advantages of provinces and cities.Sixth,it will change the traditional mode of agricultural production and increase farmers' income.
