Abstract: In order to study the relationship between economic development and dependence of agricultural mechanization on financial investment, this paper analyzes the dependence of agricultural mechanization on financial investment according to the cross-sectional data of each province across China. The results indicate that the dependence of agricultural mechanization on financial investment has a negative correlation with net income per capita of farmers, and has a positive correlation with GDP per capita. The diversified investment pattern requires that the investment proportion should achieve basic equilibrium among various investors such as government finance, farmers and collectivity. However, currently the proportion of financial investment is only 10% in the whole investment of agricultural mechanization. China is stepping into a new stage that financial support for agricultural mechanization should be intensified and agricultural mechanization becomes more and more dependent on financial investment.
