Willingness of farmers to participate in food traceability systems:improving the level of food safety

In order to solve frequently emerging food safety problems and adapt to the developing trends in the international food safety field, the Chinese government is establishing and developing food traceability systems. Whether or not food traceability sys- tems can guarantee food safety is a problem well worth discussing. Hence, we constructed a theoretical model to explore the effect of incentives in a food traceability system in order to improve food safety levels. The following results were obtained： enhancing the ef- fectiveness of a food traceability system, increasing the payment to farmers who supply safe agricultural products and strengthening the penalty for unsafe food supply actions are necessary conditions to improve the level of food safety. How to encourage farmers to use food traceability systems is another problem explored in our investigation. Based on a field survey on the willingness of vegetable growers to participate using a vegetable traceability system in Beijing, the first city in China to develop such a system, we used a de- scriptive statistics and a binary logistic regression model to investigate the factors which dominate the decision on the part of farmers to participate in a food safety system. The results indicate that i： younger farmers are more likely to get involved in a food traceability system than older farmers, ii： income from non-agricultural activities decreases the willingness of farmers to participate, iii： the high- er the cost-benefit ratio of growing vegetables, the more likely for farmers to engage in a food traceability system, iv： farmers with a great concern for food safety information have a high propensity to participate and v： increased penalties against unsafe food supply actions and high-risk expectation are adverse incentives. In contrast, high-price expectation is a positive incentive for farmers to par- ticipate, while agricultural training, government subsidies and being part of an industrial organization will significantly strengthen the confidence of farmers to participate in a food safety system.

Influence Factors of Farmers' Willingness to Poverty Alleviation Relocation in South Shaanxi Province

In southern Shaanxi,far from the core areas of politics and economy,the conditions are inconvenient and farmers have been threatened by geology,floods for many years,resulting in a large population of poor people.The relocation of poverty alleviation project in southern Shaanxi is helpful for improving living standards of people in disaster-stricken areas.Based on the field survey,this paper analyzed 274 valid questionnaires and established a Logistic Regression Analysis Model.The result shows that the health status of head of household,road type before relocation,annual loss of disasters,and changes in the family income after relocation have a greater influence on the relocation willingness of farmers,while the educational level of householder,the distance from the original place of residence to the town and market,the condition of household electricity before relocation and other factors have a little influence on the relocation willingness of farmers.

Willingness of Farmers Joining Professional Cooperatives——Based on the Questionnaire Survey of Nanjing

Based on the questionnaire survey of farmers in Nanjing City,the research analyzes the influencing factors of farmers' willingness joining professional cooperatives with Binary Logistic model.Results show that variable factors such as:labors,degrees of education,levels of awareness,development of judgments,have positive relation to the willingness of farmers joining professional cooperatives;gender and financial demands are negative related to willingness of farmers joining professional cooperatives;variable factors,such as ages,degrees of education,numbers of farmers,scale of land,generation experience,specific investment and fluctuations of prices,the estimated parameters of which are not significant.At last,the paper points out that the 2 important ways in accelerating the development of professional cooperatives are:the first is to accelerate the capital accumulation of advanced farmers and strengthen the scaled degrees of agricultural management.The second is to promote the information and techniques accumulation speed of professional farmers to strengthen people's awareness and confidence.

Factors Influencing Farmers' Willingness to Participate in the New Vocational Training

Probit model is applied to analyze some key factors influencing farmers' willingness to participate in the new vocational training for farmers based on 683 questionnaires from 8 districts in Chongqing. The results show that individual and family factors significantly affect farmers' participation will. These factors are age,family scale and years of education. Age is the most important factor,family scale is of secondary importance and years of education are the third one. Meanwhile,years of education positively affect farmers' participation willingness;there is a negative correlation among age,family scale and this willingness. Organizer,rural economic development level and training experience have no significant influence on this willingness.

Study on the Influence of Farmer Social Capital on Cooperative Supply Willingness of Agricultural Disaster Reduction Public Goods——Based on the Investigation on 515 Farmers

Based on social capital theory,related factors of three dimensions( structure dimension,cognition dimension and relation dimension) of farmer social capital are taken as independent variables,and famer's willingness to cooperatively supply agricultural disaster reduction public goods is taken as dependent variable. Taking 515 farmers in 27 villages of Hubei Province as investigation objects,the influence of farmer social capital on cooperative supply willingness of agricultural disaster reduction public goods is explored by Logistic regression model. Research results show that social solidarity,common value concept,social trust and reciprocal content have positive impact on farmer's willingness of cooperative supply,while annual household income,number of agricultural disaster reduction public goods and social network have negative impact on farmer's willingness of cooperative supply.

Factors Influencing Willingness and Ability of Farmers to Adopt New Technologies:A Case Study of Guanzhong Area

Based on data of 248 rural households in Pucheng County and Huxian County,we established the Two-Level Logit Model to analyze the willingness of farmers to adopt new technologies,its influence factors,and probability of successful adoption of new technologies.Results show that the willingness has positive correlation with whether the farmer is head of household,the educational level,occupation,agricultural loan,the number of family labor,and information dissemination channel,while it has negative correlation with non-agricultural employment proportion and whether the farmer is village cadre.In the model of the probability of farmers'successfully adopting new technologies,occupation,agricultural loan,planting area,gender and educational level are positively correlated,while age and non-agricultural employment proportion are negatively correlated.Largescale flow of rural labor plays a negative role in popularization of technologies in rural areas through influencing factors,including number of family labor,non-agricultural employment proportion,educational level,gender,and whether the farmer is village cadre.Finally,on the basis of results of empirical study,we put forward countermeasures and suggestions for strengthening ability of farmers to adopt new technologies.

Investigation on Farmers'Willingness to Participate in Rural Non-point Source Pollution Control in Nantong and Analysis of Its Influencing Factors

Based on the questionnaire survey of 337 farmers in 8 villages in Rugao City,Jiangsu Province,the gender,age and educational level of the main able-bodied people of farm households,the characteristics of farmers’production and living behaviors,farmers’cognition of rural non-point source pollution,and farmers’willingness to pay for rural non-point source pollution control and its influencing factors were studied.The results show that to protect the rural ecological environment,most farmers are willing to participate in rural non-point source pollution control,but the annual cost of rural non-point source pollution control is low,and the number of volunteer days is small.Rural grass-roots party organizations should stimulate farmers’willingness to participate in rural non-point source pollution control,give full play to the role of the branch as a fighting fortress,and build a mechanism for Party building to lead rural non-point source pollution control.

Impact of social capital on farmers' response to different policies for controlling agricultural non-point source pollution

Chinese society in rural areas is typically a geographically and genetically related society.Scattered farmers can be connected to form small groups through their social capital,which can affect farmers' agricultural activities in the process of controlling agricultural Non-point Source pollution.An ordered Logit model can be built to analyze the effects of social capital to farmers' responsive willingness to different measurements of controlling agricultural NPS pollution by using survey data in Shaanxi Province.This paper characterizes farmers' social capital in three dimensions:social trust,social participation and social network.The results indicated that farmers' social capital significantly affects farmers' response to different policies.When governments construct and implement policies to control agricultural NPS pollution,the effects of social capital need to be considered at same time with the effects of governmental supervision,market and education measurements.

Establishment of Grain Farmers' Supply Response Model and Empirical Analysis under Minimum Grain Purchase Price Policy

Based on farmers' supply behavior theory and price expectations theory,this paper establishes grain farmers' supply response model of two major grain varieties (early indica rice and mixed wheat) in the major producing areas,to test whether the minimum grain purchase price policy can have price-oriented effect on grain production and supply in the major producing areas. Empirical analysis shows that the minimum purchase price published annually by the government has significant positive impact on farmers' grain supply in the major grain producing areas. In recent years,China steadily raises the level of minimum grain purchase price,which has played an important role in effectively protecting grain farmers' interests,mobilizing the enthusiasm of farmers' grain production,and ensuring the market supply of key grain varieties.

Empirical research on impacted factor of farmer＇s willingness for purchasing information Based on the survey data of Hebei province

Farmer＇s willingness for purchasing information, an important factor of farmer＇s information demand, was analyzed by logit model, according to the survey data of 535 farmers from eleven cities in Hebei province. The result showed that 6 factors had a significant influence on it, that is, education of farmers, per capita income of farmers, the affordability of information risk, the proportion of agricultural labor households, the type of agricultural production and the rural information service stations. On the basis of these, the related policy recommendations were proposed.

Behavior configuration of tea farmers’ participation in ecotourism environmental responsibility from the perspective of system theory

The coordination and optimization of eco-tourism development and world heritage protection are related to the sustainable development of the two,and the behavior of tea farmers is affected by the multiple subjects of rural production and living system,which has nonlinear and complex characteristics.In view of this,based on the theory of human-land system,this study is using system theory and fuzzy set qualitative comparative analysis(fsQCA)to explore the internal mechanism of tea farmers‘environmental responsibility behavior.The results show that:(1)single factor,infrastructure environment perception constitutes a necessary condition for environmental responsibility behavior,and there is equivalence between infrastructure environment perception,Cultural environment perception,external intervention perception and environmental supervision perception.(2)Infrastructure environment perception and cultural environment perception are important internal driving forces for high environmental responsibility behavior,while external intervention perception and environmental supervision perception constitute external traction.(3)Infrastructure environment perception and cultural environment perception exist in all configurations in a single or common form.This provides enlightenment for changing the governance logic of ecotourism and improving the governance performance of ecotourism.

Empirical Analysis on Rural Financial Development and Farmers' Income Increase in China

The growth of farmer＇s incomes is cIoseIy reIated to rural finance. The research analyzed the dynamic reIationship of rural financial deveIopment, efficiency and farmer＇s incomes based on VAR modeI, and the resuIts indicated that the ex-pansion of rural finance wouId stimuIate farmer＇s incomes in a Iong term, and the growth of rural financial efficiency significantIy improves farmer＇s incomes in a short term, instead of a Iong term. Hence, it is necessary to introduce more credit funds and social funds to rural areas, deepen rural financial system reform and acceIerate use rate of Ioan capital and enhance guidance for farmers and township enterprises in use of Ioan capitals.

Factors influencing farmer willingness to plant forage triticale in winter fallow fields in Northern China:An example from central Shanxi Province

Background:Using winter fallow fields for plant forage is important to ensure food security.Forage triticale(×Triticosecale)has higher yields than other available forage crops and can be planted widely in winter fallow fields.Recently,the planted area of forage triticale in Shanxi Province,China,has exceeded 3500 ha;however,problems such as low farmer willingness to plant(WTP)winter forage still remain.Methods:A total of 219 farmers were surveyed in Taiyuan,Lvliang,and Jinzhong.We analyzed the factors influencing farmer WTP forage triticale,focusing on personal,family,land,and cognition characteristics.We used a binary logistic regression model to quantify the influence of various factors on farmer behavior and conducted a robustness check and heterogeneity analysis.Results:“Age”was negatively correlated with farmer WTP—farmers 50 years of age and older showed less WTP.“Land lease situation”was also negatively correlated with WTP.Factors that positively correlated with WTP were“land areas,”“raising of livestock,”“size of labor force,”and“development prospect.”Conclusions:Many farmers are over 50 years of age,land lessors,and have low WTP winter forage.Farmers who raise livestock and have large labor forces,huge land areas,and good cultivation prospects have a high WTP.This study identifies the factors influencing farmers'WTP to assist in the development of the forage triticale industry in the study region,improving land resource utilization and efficiency.The findings are likely to have wider relevance and application.

Analysis of the Dynamic Relationship among Financial Fund for Agriculture, Agricultural Output Value and Farmers' income

By using the methods of co-integration, impulse response function and variance decomposition, I conduct the empirical research on the dynamic relationship among China's financial fund for agriculture, agricultural output value, and farmers' income from the year 1978 to the year 2009. The results indicate that the government's financial fund for agriculture plays the significant role in promoting agricultural output value and farmers' income in the long run, but this role of promoting is not prominent in the short run; in the mean time, agricultural output value plays insignificant role in promoting farmers' income and the government's financial fund for agriculture; farmers' income plays the significant role in promoting agricultural output value and the government's financial fund for agriculture.

Empirical Analysis on Effect of Agricultural Financial Investment on Increase of Farmers' Income

On the basis of economic data from 1978 to 2006,the co-integration theory is applied to discuss the relation between agricultural financial investment and farmers' income.The statistic AR model is obtained.Then,it makes pulse response analysis in combination with principle of pulse response analysis.The regression results show that support in agricultural production,various agricultural operating expenses and three types of costs for agricultural science and technology are favorable to farmers' income,while expenditure in agricultural capital construction and rural relief costs hinder increase of farmers' income.The results of pulse response analysis indicate that the change in support of agricultural production and various agricultural operating expenses have positive impact on farmers' net income,and the impact is greater and greater from the second year;the response of expenditure in agricultural capital construction and rural relief cost is positive in the beginning and starts to fluctuate from the third year;the pulse response of three types of costs for agricultural science and technology is negative,lasts about five periods,and then turns to positive impact.Finally,combining characteristics of China's financial support for agriculture,it concludes that the scale,proportion and structure of financial support for agriculture are quite improper.

Dynamic Relation between Rural Human Capital and Farmers'Income in Henan Province

We use relevant economic and labor force data from 1990 to 2009 of Henan Province to analyze the dynamic relation between stock of rural human capital and farmers' income.Results indicate that a certain causal relationship and long-run equilibrium relation exist between rural human capital and farmers' income,but their interaction shows some lagging characteristic.Increase of farmers' income in Henan Province increases the stock of rural human capital in this province for a short term.However,in the long run,this accumulation effect will decline along with renewal and aging of knowledge.The positive promotion action of rural human capital on farmers' income will appear after a long lag time.Therefore,the policy of strengthening rural human capital input should be long-term and continuous.

基于期望效用理论的农户土地整治权属调整意愿研究

基于期望效用理论剖析农户土地整治权属调整意愿的内在机制,以广西壮族自治区龙州县的农户调查问卷数据为基础,采用逻辑斯谛(Logistic)模型,分析不确定条件下未来的预期收益和预期损失效用对农户权属调整意愿的影响,为引导农户积极响应权属调整提供决策参考。结果显示:农户认知是其产生支持行为意愿的基础,研究区只有约20%的农户对权属调整政策比较了解,超过80%的农户通过“自上而下”的方式被动获取信息,但接近90%的农户对权属调整表示认同,说明政策实施具备民意基础。在未来预期收益方面,新增耕地面积、改善农业基础设施条件、提高农业机械化使用率、提高规模化经营程度等因素对农户权属调整意愿至少在P<0.1水平上有显著正向影响;在未来预期损失方面,耕地质量下降、土地分配不公平等因素对农户权属调整意愿至少在P<0.05水平上有显著负向影响。据此提出如下对策建议:加强权属调整全过程的农户有效参与,切实保障农户土地权益;完善权属调整的法治化建设和制度化管理,促进权属调整获得农户的支持和信任;发挥权属调整对农地适度规模经营的推动作用,促进农户分享现代农业发展红利。
