Comparative Analysis On The Planting Advantage To Maize And Alternative Crops Based On The Perspective Of Household

In recent years,with the impact of soybean imports,domestic soybean acreage have been reduced,while farmers prefer to planting maize and lead to maize yield increased dramatically,to 2014,the proportion of maize planting area is about 31.5%.Numerous studies have also pointed out that maize planting in the way of squeezing other crops' area has become the main force of grain production in China.However,maize plant squeezes money,labor and land from other crops,resulting in the insufficient supply of agricultural products directly and the oversupply in maize.The phenomenon is disadvantage to increase advantageous crop.Therefore,"appropriate scale down the edge section corn,expand LiangGai feeding pilot" became the maize supply side structural reform direction in the future.In this paper,based on considerations of regional differences,with major maize producing province farmers as the research object,it aims to answer the opportunity cost of maize production between regions?Which areas conforms to the principle of comparative advantage?How to adjust maize planting structure to us in the future?Which reasons to interpret economic rationality of farmers' decision-making behavior differences between different region.In order to achieve the above objectives,this paper made the following several aspects work and the corresponding conclusions:l.The opportunity cost of producing corn production difference and corn planting.On this basis,using partial least squares model and factor contribution rate formula to measure price,yield,cost,mechanization and policy-related subsidies for corn and its main alternative crops,the contribution rate of net income,to further explore the path selection of structure adjustment of corn farmers.Results show that the unit output and price is still the greatest contribution of corn farmers net earnings growth factors,corn high yield level makes its unit production cost is low;Control the excessively rapid growth of physical capital,will be good for farmers adjustment.2.Verify the current crop planting structure fit with farmers decision-making of the first economic goals and give explanations.Farmers decision-making behavior is due to the combination of the inside and outside.,because,in this paper,different areas of urbanization and mechanization production brought about by the element configuration and element substitution effect on the decision-making behavior of corn farmers;In the external level,this paper discusses the natural endowments and policy support for corn farmers to choose.(1)Based on the theory of element configuration and element substitution theory and related theory,analyzed the urbanization under the background of factor endowments change's impact on corn farmers to choose.Research results show that the population urbanization brought about by the labor and capital element substitution effect,the higher degree of social services of corn comparative advantage highlight out slowly,so farmers often adjust corn and alternative crops,relatively more tend to reduce labor intensive alternative crops planting proportion,and raise the proportion of the capital-intensive corn planting;Although capital for labor elements of the substitution effect on agricultural production has a role in investment,but this kind of investment is still limited,there is no significant difference among choice for growing crop(2)The gap to analysis the economic efficiency of the decision-making behavior of corn farmers.Farmers behavior advantage is not completely accords with the principle of the first economic goals,we need to explain from peripheral factors.Plant growth depends on the local natural conditions.This paper based on corn and alternative crops natural growth condition and the agricultural support policies of comparative analysis,to explore the natural resources endowment(including water conservancy,land and finely)and policy support for corn farmers to choose.Found that due to the condition of rainfall and its alternative crops are corn,not high demand of farmland level facilities will not affect the decision-making behavior of corn farmers.However,with the popularity of mechanization production,land and finely degree has become an important factor of corn farmers decision-making.
