Abstract: Based on the function model of agricultural production, and using the ridge regression method, this paper analyzed the influence of labor, capital, land and technology on agricultural economic growth in different types of agricultural regions. The research shows that: (1)the elastic coefficients of input elements in the reclamation areas are greater than that of the common agricultural areas, which means that the modern agricultural production mode has more advantages than the traditional production mode. (2) the input factors, such as labor, capital and land, have significant impact on both reclamation area and common agricultural area. The reclamation area is in the stage of increasing return to the input scale, which is opposite to the common agricultural area. (3) the progress of science and technology is also an important factor that affects the agricultural economic growth in both reclamation area and common agricultural area, which accounts for 45.3% and 42.5% respectively. The reclamation area should play its advantages of technology, management and resources, and participate in the cooperation actively with the common agricultural area around it, and cultivate and develop the reasonable farm- county (city) cooperation mode based on the local conditions. While the common agricultural area should develop moderate scaled management, and optimize the investment structure of agricultural factors, so as to improve the comprehensive efficiency of agricultural production and promote the sustainable development of agriculture.
