消费者水产品质量安全支付意愿影响因素分析——以湖南娄底市城镇居民为例

论文通过对湖南娄底市消费者问卷调查数据,并利用SPSS统计分析软件对影响消费者水产品质量安全支付意愿的变量进行研究分析,结果显示：消费者的受教育程度、性别、家庭月收入、每月农产品花费、年龄因素对消费者水产品质量安全支付意愿有较大影响,但消费者受教育程度、性别与支付意愿呈负相关关系。并在此基础上提出相关建议：加大对水产品质量安全知识的宣传和普及;加大对认证水产品的补贴;在超市和农贸市场做好定点宣传和推广工作;制定切实可行的可追溯安全水产品营销战略。     

Do Japanese consumers care about sustainable fisheries? Evidence from an auction of ecolabelled seafood

This paper investigates Japanese consumers' willingness to pay for Marine Stewardship Council (MSC) ecolabelled seafood using a sealed bid, second price auction. Participants in an experiment in Tokyo were provided varying degrees of information about the status of world and Japanese fisheries and the MSC program in sequential rounds of bidding on ecolabelled and nonlabelled salmon products. A random‐effects tobit regression shows that there is a statistically significant premium of about 20 per cent for MSC‐ecolabelled salmon over nonlabelled salmon when consumers are provided information on both the status of global fish stocks and the purpose of the MSC program. This premium arises from a combination of an increased willingness to pay for labelled products and a decreased willingness to pay for unlabelled products. However, in the absence of experimenter‐provided information, or when provided information about the purpose of the MSC program alone without concurrent information about the need for the MSC program, there is no statistically significant premium.

Willingness to Pay and QALYs: What Can We Learn about Valuing Foodborne Risk?

This paper examines the value of reducing foodborne risk. Previous research on the valuation of health risk has been dominated by the study of mortality risk. However, in most cases foodborne illnesses are non‐fatal, so we focus on individuals' preferences for reducing morbidity risk, while also including a realistic, if remote, chance of death. We use a contingent valuation method on a Swedish sample and we estimate a value of a statistical illness consistent with previous findings in the literature. We also examine how willingness to pay (WTP) varies with the expected change in quality‐adjusted life years (QALYs) and estimate the WTP per QALY. We find that WTP increases with, though less than proportionally to, a change in QALYs. However, our results also suggest that respondents may have found it difficult to evaluate compound risks of both morbidity and mortality simultaneously.     

林农参与区域性林业科技信息资源平台构建行为的实证分析——以陕西省为例

基于陕西省林业科技信息资源平台发展现状,利用因子分析和Logistic回归模型,深入剖析林农参与林业科技信息资源支付意愿及其影响因素。结果表明:受访林农中愿意为获取科技信息而支付意愿为53.6%,说明林农对于林业科技信息资源平台的接受程度比较高;受访者的经济来源、生产经营、认知情况、参与行为等4个因子变量对林农的参与行为具有显著影响,林农愿意支付与否主要取决于其经济水平。因此,提出增加科技投入,加强农村信息基础设施建设;加强林业科技信息资源平台队伍建设;大力发展农村经济,推进信息服务多样化;规范信息有效性,建立健全林业科技信息资源监督机制等建议。     

Consumer response evaluation of a greek quality wine

This paper reports on the attempt made to identify consumer response on certified quality wine with a destination of origin (PDO) indication. Given that the current consumer interest in quality food has increased, it is important to measure their level of awareness of and overall behaviour towards these products. Emphasis is given on quality wine, produced in the region of Peza, Crete, which is labeled as a cooperative PDO product with high quality standards. A survey that utilized a self-administered questionnaire was designed to obtain the data needed for the study that took place in the Attiki region. Consumers who participated in the survey were asked to indicate (i) their general level of knowledge on PDO products and on Peza cooperative wine in particular, (ii) their attitudes towards several quality attributes, considered when buying and consuming wine, (iii) their intention to purchase a higher priced Peza cooperative wine with a quality certification and PDO indication label. The results seem to be important for all the market bodies that are involved in the supply chain of this product since they may be a guide to developing production and marketing strategies that instil consumer confidence, assure consumer satisfaction and therefore satisfy demand.     

Consumer’s Preference and Willingness to Pay for Apple Attributes: A Choice Experiment in Large Retail Outlets in Bologna (Italy)

ABSTRACT

We analyze the relevant quality attributes of apples which drive and influence consumer choice in the city of Bologna (Italy). A hypothetical choice experiment was conducted to elicit Italian consumer’s willingness to pay for apple attributes and was included as a part of a questionnaire survey. A group of 301 consumers were surveyed in Bologna in July and August 2016. Data were analyzed using a multinomial logit model. Results suggest Italian consumers are willing to pay more for yellow apples and for apples harvested in Trentino-Alto Adige region, compared with other Italian areas. Furthermore, results highlight a preference for locally produced apples, whereas organic apples are only slightly preferred to the not organic alternative. Results of this study could be used to develop marketing strategies for apple differentiation or for a new product development and target the right product to the right consumer.     

Trade-offs between consumer concerns: An application for pork supply chains

This paper studies, by means of customized conjoint analysis, the trade-offs that Dutch consumers make between multiple pork-production attributes, and their relation to consumer concerns. Results show that attributes that deal with animal welfare and food safety are on average perceived as the most important pork-production attributes. Not surprisingly, they are less important than the product attributes taste and price. Still, a number of market segments can be identified in which taste and price are relatively less important. Results support the implementation of differentiated chain designs with distinct and innovative decisions on trade-offs to be made, such as with respect to the housing of pigs and the use of genetic modification.     

Willingness to pay for credence attributes associated with agri-food products—Evidence from Canada

Credence attributes such as environmental impact, origin, fairness/unfairness, and food safety/health are not available with certainty prior to or at the time of the consumer purchase decision. This creates a problem of imperfect or asymmetric information, leading to suboptimal supply and demand for products with these desirable attributes. Using a representative sample of 2001 Canadian consumers, we adopt, within an attribute-based decision-making framework, the asymptotically efficient double-bounded stated preference approach, to estimate Canadian consumers' willingness to pay for origin, fairness, environmental impact, and food safety attributes associated with pork chops and fresh apples. We find that, on average, consumers are willing to pay significantly more for pork chops and fresh apples that are farmers-advantaged, sourced from their own province, grown or raised under a production system designed to be environmentally sustainable, and chemical-free. However, these findings differ significantly by the province of origin, gender, age, and income of the respondents, as well as by product type and attributes being valued.     

Consumers' Willingness to Pay for the Color of Salmon: A Choice Experiment with Real Economic Incentives

In most retail markets, sellers post the price and consumers choose which products to buy. We designed an experimental market with posted prices to investigate consumers' willingness to pay for the color of salmon. Salmon fillets varying in color and price were displayed in twenty choice scenarios. In each scenario, the participants chose which of two salmon fillets they wanted to buy. To induce real economic incentives, each participant drew one binding scenario; the participants then had to buy the salmon fillet they had chosen in their binding scenario. The choice data were analyzed with a mixed logit model.     

Decomposing Local: A Conjoint Analysis of Locally Produced Foods

Increasingly, foods are marketed as locally grown. We use stated preference data from a choice-based conjoint instrument to address two issues surrounding consumer demand for locally produced goods: (1) what is the geographical extent of local, and (2) is the value consumers place on local production distinct from other factors that are often confounded with locally produced foods such as farm size and product freshness? We find our subjects place similar value on products produced in state and nearby and that consumers' willingness to pay for local production is independent from values associated with product freshness and farm size.
