Study On Camellia Oleifera Abel Supply Based On Farming Household's Economic Perspective

Food security and its socio-economic impact has attracted worldwide attention. The strong constrain of agricultural resources faced by China and the upgrading of the structure of dietary become increasingly prominent, and the shortage of high-quality edible oil supply has been an important problem which impacts on China's food safety strategy. Because of the benefits of not occupying cultivated land and the good features of woody oil, policy-making authorities and academics start to focus on the development of Camellia oleifera Abel industry. Camellia oleifera Abel industry has economic, ecological and social benefits, which can not only improve the business model of sustainable forestry, but also give full play to China's rich forest resources in the capability of food supply. However, many important issues related to the development of Camellia oleifera Abel industry at this stage are still unknown, of which the largest uncertainty reflected is the problem of insufficient supply. The economic feasibility and the supply potentiality of raw materials are the key to determine the development of Camellia oleifera Abel industry, and the supply potentiality mainly depends on the per unit area yield and planting area. As the main supply body of Camellia oleifera Abel is farmer, therefore, in addition to natural constraints, the determination of input behavior and decision-making of growing area is depended on the characteristics and decision-making mechanisms of farming household. These problems have important practical significance, but there have not got systematic empirical researches currently.Therefore, the overall objectives of this study are to grasp the present situation and its main influencing factors of Camellia oleifera Abel industry from micro level, to reveal the relationships between input and output, based on which to simulate the supply potentiality of Camellia oleifera Abel in different situations. Then through the empirical research on supply behavior causes and decision-making mechanisms, validates and analyzes the present situation and conditions to achieve the supply potentiality of Camellia oleifera Abel industry, which can provide empirical evidences for the constituting and extending of the development policies of Camellia oleifera Abel.To achieve the objectives of this study, the research comprehensively uses of normative study and empirical study, qualitative and quantitative methods of economics, operational research and sociology, which mainly involves the following six parts: (1) Analyses the history and present situation of Camellia oleifera Abel industry as well as the industrial policy changes to describe a clear picture of the development of Camellia oleifera Abel industry, laying the foundation for the analysis of the main factors affecting the supply of Camellia oleifera Abel. This part includes the second and third chapters. (2) Using farmers'supply behavior theory and behavioral science theory, the paper constructs the supply factors framework of Camellia oleifera Abel farming households. On this basis, constructs the production function and supply decision-making model of Camellia oleifera Abel, laying a foundation of theoretical framework for the text structure. This part includes the fourth chapter. (3) Applying interview questionnaire survey method to design questionnaire and collect data based on input-output land blocks. Using statistical analysis method to depict the behavioral characteristics of Camellia oleifera Abel farming households and make the economic evaluation, providing basis for proposing hypotheses and building supply decision model from micro level. The main contents are the fifth and sixth chapters. (4) Takes use of econometric models, expert interviews to estimate and correct the production function model of Camellia oleifera Abel. Uses linear programming theory to slove the optimal relationship between input and output, simulate the potential supply of Camellia oleifera Abel in different situations, and evaluate the socio-economic conditions to achieve the planning objectives. The main contents are the seventh and eighth chapters. (5) Use binary logistic regression analysis, net present value method to quantitatively measures farming household's will to supply Camellia oleifera Abel and factors that affect the will, and use case studies to reveal the supply decision-making mechanism of Camellia oleifera Abel farmers. The conclusions are used to validate the current supply status, the main factors and the social and economic conditions to achieve supply potentiality of Camellia oleifera Abel. This part mainly includes the ninth and tenth chapters. (6) Promotes policy recommendations according to the study conclusions. Include the eleventh chapter.Through theoretical and empirical research, the paper reaches the following conclusions: (1) From the macro level, the supply capacity of raw materials is less than the planed processing capacity of Camellia oleifera Abel, and the development of Camellia oleifera Abel market is not yet mature. (2) From the micro level, the status of resources allocation for Camellia oleifera Abel is low in the farming households. Because of the poor quality, small-scale land parcel and the low level of tending, the per unit yield and economic benefits of Camellia oleifera Abel is relatively low. (3) Factors that affect the per unit yield of Camellia oleifera Abel are cumulative input, the current labor input and the suitability of forest land. Because the input of fertilizer is seldom at present, the effect of fertilizer is temporarily inapparent. (4) According to the conclusion based on the solving of Camellia oleifera Abel supply decision-making model, the current input-output relationship is not yet optimal, especially for fertilizer input. So there is a great potential for growth in Camellia oleifera Abel supply. (5) The simulation results of Camellia oleifera Abel supply potential shows that the top 3 provinces have the greatest Camellia oleifera Abel supply potential are Hunan, Jiangxi and Fujian Province. But in the current input-output level, even under the high growth program, it is also difficult to achieve the development objectives of Camellia oleifera Abel. Only when making a difference on elasticity of factor inputs, Camellia oleifera Abel product prices, factor prices, the discount rate and other socio-economic conditions can the development goals be achieved. (6) For the supply will and decision-making mechanism of Camellia oleifera Abel, farmers'enthusiasm to plant Camellia oleifera Abel is not high, which mainly due to the comparative low income, industrial policy that not fully demonstrated effects, incomplete market and imperfect social service system.Based on the above conclusions, this paper makes the following recommendations: (1) The development of Camellia oleifera Abel industry is realistic and urgent, but it is necessary to formulat appropriate developing goals and to enhance the realizability of developing goals through improving tending level of Camellia oleifera Abel. (2) It is necessary to increase farming households'supply will through the expansion of technologies and strengthening the effect of policy incentive and other means to reduce the cost of unit area yield of Camellia oleifera Abel supply. (3) Expand demand of Camellia oleifera Abel by cultivating raw materials markets and clear market positioning, which can immit stable power for the supply of Camellia oleifera Abel.Given there was little literature studying the supply of Camellia oleifera Abel from economic perspective of household, but the supply of household decision-making is the key to determine whether the Camellia oleifera Abel industry will develop successfully, this study is innovative in perspective and content. This paper also makes some new trial in research methods by combinating of econometrics, operational research and sociology methods. In addition, the conclusions of this study evaluates the policy objectives and proposes the conditions for implementation, which has some practical value. However, due to the limited research conditions, the collection of data is limited to farming households in Fujian Province. Also because of the long growth cycle of Camellia oleifera Abel, the new created Camellia oleifera Abel in recent 5 years which is on behalf of a higher tending level has not yet put into production. Only after the holocarpicing of this part of sample can we obtain a larger scale of input-output data to better reflect the status and potential supply of Camellia oleifera Abel. Therefore, this issue needs further concern and future research.
