The Change Of Grow Grain Research On The Impact Of Food Security And Countermeasures

Grain is not only a strategic material for the people's livelihood, but also the people's most basic living materials; it is both the foundation of social stability and national security. Although the experts are divided about the judgement of China's food security, one consistent aspect of China's food security is in a tight balance. Even the total grain output of China reaches 12 times increases during the period of 2004-2015, which can be considered as a miracle in the history of China and the world. However, it still can not be taken lightly, we have to face with trouble caused by the growth of grain production, inventory and imports, and the deterioration of the ecological environment, increasing financial pressure, grain quality decreased.Food security refers to grain production, circulation, consumption import and export. But many studies show that as a large country of grain consumption, it can use the international grain market, but it's not wise to relies on it. Therefore, it is the only way to base on the domestic market, "Chinese must hold it at any time." Based on the supply and demand, with the development of economic and the growth of population, rigid demand of grain is obvious, although irrational consumption patterns lead to the food waste, but the key issue of food insecurity is the insufficient of supplyment and structural imbalance,furthermore for the difficulty of changing market needs. Therefore, the core of food security is safety production and improve the food supply in the new normal.The food security includes the safety in numbers and safety in quality, but also includes the ecological security and other aspects of the content. In the new normal, the main contradiction between grain supply and demand has turned to structural contradictions.The people who plant the food, under the rising pressure of international prices and domestic production costs, the enthusiasm for growing grain is greatly weakened. Futhermore, the deep changes under new normal economic and social structure, lead to the behavior changing of main body in land use, grain planting,technology selection and storage, grain sale,etc. Those changes may have great influence on food quantity security, quality security and sustainable development. Therefore, in the new normal, it is urgent to analyze the mechanism of grain behavior change and on food security and the reality, the potential impact, reevaluation of the applicability of conclusions previously made, policy recommendations of rationality, in order to provide a sufficient basis for national policy adjustment and optimization, to mobilize the enthusiasm of the main grain and to optimize its behavior mode, effectively enhance food security objective, deeply and systematically.In order to fully grasp the changes of planting grain body's behavior in the new normal and its impact on food security, and propose countermeasures targeted and operability, based on food production, topography, geography and economic development, this paper select Xinjin County (Chengdu), Deyang Guanghan City, Zigong Rongxian, Guangyuan Cangxi, Yibin Junlian as a goal, to conduct fieldwork, combined with macro data and existing research results to make analysis. In addition to the full text of the introduction, mainly to carry out research in the following eight areas:Firstly, to define the important conception related to food security, grain and other key definition. To argue and comment on domestic and foreign research literature, which focusing on the behavior of grain cultivated land use, food production, food reserves, technology choice, and food sales. Combined with farmers act theory, social cognitive theory, incentive theory and prospect theory, to analysis the grain actors theoretical, to provide scientific guidance for the further study of this article.Secondly, from three aspects, i.e.:food demand, supply and international markets on food security issues, analyze and build food security evaluation system. Based on the reaction of ecological food quality and safety indicators into the assessment scope drawing on existing research results. Make the index into three categories, positive indicators, reverse indicators and interval factor. Make quantitative analysis by using food safety and food security early warning for food security evaluation. Make pre-judgment for contradictions of regional and global food shortages, the trendency of changes for domestic demand the environment supporting capacity, the increase of grain, and so on.Thirdly, analysis the impact on food security in Sichuan, include food security and the current situation of Sichuan, slowing down of the growth under the new normal, the demand for upgrading of the structure, power conversion and support the development of policy adjustments.,and Sichuan food security situation of supply and demand analysis. Elaborate food production profit and increasing farmers' income and demand become more prominent, agricultural land relations quick adjustment and subsidies deviation contradictory food intensifies, the traditional mode of production to quickly collapse and new agricultural business entities foster lag double contradiction, food-scale operation of land non agricultural, non-grain-oriented co-exist, the family stored grain farmers and other support functions to quickly weaken the multiple challenges of Sichuan food security.Fourthly, the use of arable land elaborate function, circulation and current situation of food cultivation, analysis of the main grain cultivated land use change attitudes and methods.Then make analysis of non-grain-oriented, extensive technology, farming and other short-term behavior. Distinguish different kinds of grain body type and regional grain-producing counties and non-grain-producing counties in the presence of arable land-use behavior, and to analyze change on food production, affecting the quality and sustainability of the body caused by the use of arable land to grow grain behavior.Fifthly, analyze inefficient grain production, inadequate social services supply, as well as the difficulty of finance and labor allocation. To analyze the behavior changes, as subsistence economy, status shift, scattered small-scale start to a moderate scale. To explain the behavior differences in food policy effect, services and investment and its impact on food safety and quality plantings caused by food production in different subjects.Sixthly, described the characteristics of technology selection, risk aversion and dislocation of supply and demand, analyze the trendency of technology diversification, labor input reduction,distinguish technology choosing attitude, purpose and content of regional differences, the main body's difference, the constraint factors in using the new technology. Full-scale analyze the behavior changes of grain body on food security.Seventhly, make analysis of grain storage, the proportion of the food, sales, information sources, and influence factors, and intrinsic factors of grain store and sales change, and explain the influence for state reserve of food and food insurance.Eighthly, analyse and evaluate the behavior of the grain plant. Combined with the analysis of food security situation and trendency, show the guidance, object, support areas and promotions.,and then make a detailed proposal.Through field research and theoretical analysis, this paper, based on the above content, may have the following innovations:(1) Research on food security from grain Actors Microscopic Perspective. Existing literature mainly from cultivated land, water resources, production, storage technology and the acquisition and subsidy system, the international market and circulation mechanism of research perspective food security problems, even to study the issue of food security from subject differentiation or behavior change perspective, those literature seldom combine them together. From the research, they are strongly interralted. I think the main grain is the microcosmic basis of food security. The change of grain behavior, is an important factor affecting food security, especially fluctuation on grain yield and quality changes, and will discover the differences in behavior. It can makes a highly individualized and operable suggestion.(2) The impact on the comparative effectiveness of enthusiasm for growing grain is greater than the absolute benefit.I think that grain is the main body of the behavior decision is not the main cost accounting and absolute cost, but the opportunity cost and the relative cost. Therefore, it is necessary to improve the enthusiasm of the main grain, not only to improve the absolute benefit of grain production, but also improve the efficiency, unchanged at risk, even if the absolute benefit of grain production increase, as long as the comparative effectiveness of decline, main grain enthusiasm will continue to decline. Therefore, it is proposed that, at least to maintain the comparative effectiveness of grain production in order to ensure the enthusiasm of grain production.(3) Reasonable incentive policy is the key to self-promote rational collective rationality.I think, in existing resources, under the restriction of system and market environment, grain subject differentiation and behavior change is inevitable and reasonable, but individual rational decision has led to the collective non-rationality, especially in view of the problem of food security in the public property, therefore, it must be led by the government resources, system and market environment change and constraints, to promote and guide the grain main differentiation and behavior optimization, so as to realize the individual rationality and collective rationality, and enhance food security ability together.(4) The integrated use of quantitative indicators of grain quality indicators and ecological indicators in order to fully reflect the true state of food security. In this paper, in the use of food security early warning for food security evaluation method to evaluate the fertilizers, pesticides and utilization of the central grain quality compliance rate, deposit rate should reflect the quality of food and ecological security indicators into the scope of the evaluation, to a certain extent, make up the existing food safety assessment method limited to the amount of food safety evaluation, and food quality and ecological safety evaluation lack deficiencies.(5) The use of multi-disciplinary theory to grain body were analyzed. Although farmers differentiation and behavioral changes of an economic behavior, but not exclusively economic behavior, the use of economic theory only analyze enough. Therefore, the paper uses household behavior theory, expectancy theory, prospect theory, social cognitive theory to grain body differentiation and behavior changes of the analysis, a more comprehensive and objective understanding of the cause and mechanism of differentiation and change.Although this may exist in the innovation, but by the personal ability and limited data, this study also has the following shortcomings:one is in the questionnaire survey, due to the large and cooperative research point limit, the representation of the data needs to be further improved. The other is the use of research information for qualitative and quantitative analysis, but the modeling analysis is still not enough, the theoretical analysis need to be further in-depth.
