Cost-Benefit Analysis Of Facility Tomato Planting In Hebei Province

Facility agriculture has a history of about 70 years in China,but it has developed rapidly and matured gradually during this period.At present,facility planting in China is mainly used in vegetable planting,such as facility cucumber,tomato,pepper,eggplant and so on.Facility tomatoes are widely planted in Hebei Province,and the planting area in 2017 ranks first in the country.However,compared with adjacent provinces and open-field tomatoes,it has no obvious advantages in cost and benefit.The purpose of this paper is to arrange the factors that affect the benefit of facility tomato planting in Hebei Province by combining statistical data with multiple regression linear model in order to reduce the cost.Therefore,this paper studies the cost and benefit of facility tomato planting in Hebei Province,and analyses the specific factors and reasons,so as to enhance the benefit of facility tomato and promote the development of facility agriculture.The exhibition is of great significance.Combining with the relevant literature,through collecting and sorting out the relevant data of "National Collection of Cost-benefit Data of Agricultural Products" and "Hebei Rural Statistical Yearbook",using descriptive analysis and other methods,this paper analyzed the current situation,planting cost and planting income of facility tomato in Hebei Province.It was found that the cost of facility tomato planting increased year by year,but the output value,net profit and cost-profit ratio were out.There is a large fluctuation and a downward trend.Using comparative analysis method,the cost-benefit of facility tomato planting in Hebei Province in recent years was analyzed vertically,and the cost-benefit of facility tomato planting in Hebei Province was compared horizontally with five adjacent provinces,facility tomato and open-field tomato.It was found that facility tomato planting in Hebei Province had advantages in labor cost and land cost compared with other provinces,but material and service costs were in the middle of other provinces.Compared with open-field tomatoes,the cost of protected tomatoes in Hebei Province is higher than that of open-field tomatoes,but from the data of cost-profit ratio and inputoutput ratio,the benefit of planting protected tomatoes is lower than that of open-field tomatoes.This paper establishes a multiple regression linear model,choosing net profit as dependent variable,land cost,labor cost,unit yield,fertilizer fee,pesticide fee and price as explanatory variable.By analyzing the panel data of 2008-2017,we can see that unit yield and price are positively correlated with net profit,land cost,labor cost and pesticide fee are negatively correlated with net profit,and other cost items are negatively correlated with net profit.There is no obvious linear relationship between profits.According to the results of various research methods,the countermeasures and suggestions were put forward,such as reducing the land cost of facility tomato,increasing investment in science and technology,improving the level of mechanization,developing large-scale planting,speeding up the transformation of traditional production mode,improving the quality of vegetable farmers,vigorously introducing scientific and technological talents,and expanding sales channels.The innovation of this paper lies in taking Hebei Province as the research area,comparing the cost-benefit of facility tomato planting in Hebei Province with the trend analysis based on macro-data,using the multiple regression linear model to analyze the formation of influencing factors to Chengdu,and according to the analysis results,putting forward pertinent proposals to promote facility farmers in Hebei Province.Suggestions on the development of industry and facility tomato industry,improving the input-output efficiency of facility tomato and increasing farmers' income.
