Study on the Development of Total Power of Agricultural Machinery in Jilin Province—Based on Principal Component Analysis
摘要
Abstract
As the food great province , it is very crucial to the development of agricultural mechanization in Jilin Province.This paper analyzes the total power of agricultural machinery and the influence factors by principal component analysis method using the relevant data of Jilin Province during 1994-2013 .The multi linear regression model is estab-lished for variable ZY and independent variables by ZX1-ZX9 .In the model , only the rural Engel coefficient and the to-tal power of agricultural machinery is negatively correlated , the rest of the independent variables are positively correlated . The coefficient of per unit area yield of grain is 0.207, and the coefficient of farmers'education level is 0.276, relatively low.And the coefficients of the other independent variables have little difference between 0.34~0.37.Finally, it put forward to strengthen the elements of macro capital support , micro production and technology input in the future in Jilin Province .In addition , it need to strengthen the cultivation of new peasants occupation , to meet the demand for talent and technology of agricultural development in the new period .关键词
