Abstract

Purpose

Conventional frequent itemsets mining ignores the fact that the relative benefits or significance of “transactions” belonging to different customers are different in most of the relevant applied studies, which leads to failure to obtain some association rules with lower support but from higher-value consumers. Because not all customers are financially attractive to firms, it is necessary that their values be determined and that transactions be weighted. The purpose of this study is to propose a novel consumer preference mining method based on conventional frequent itemsets mining, which can discover more rules from the high-value consumers.

Design/methodology/approach

In this study, the authors extend the conventional association rule problem by associating the “annual purchase amount” – “price preference” (AP) weight with a consumer to reflect the consumer’s contribution to a market. Furthermore, a novel consumer preference mining method, the AP-weclat algorithm, is proposed by introducing the AP weight into the weclat algorithm for discovering frequent itemsets with higher values.

Findings

The experimental results from the survey data revealed that compared with the weclat algorithm, the AP-weclat algorithm can make some association rules with low support but a large contribution to a market pass the screening by assigning different weights to consumers in the process of frequent itemsets generation. In addition, some valuable preference combinations can be provided for related practitioners to refer to.

Originality/value

This study is the first to introduce the AP-weclat algorithm for discovering frequent itemsets from transactions through considering AP weight. Moreover, the AP-weclat algorithm can be considered for application in other markets.

Abstract

Purpose

The selection of purchasing channels by wine consumers indirectly affects buying experience and satisfaction, therefore, it is of great practical significance to study consumers' preference on channel selection. The purpose of this study is to investigate the current state of consumer selection for purchasing channel and the corresponding influencing factors.

Design/methodology/approach

A total of 2,976 valid questionnaires were collected by convenience sampling from 34 provinces, municipalities and autonomous regions of China in 2020 via the Internet, yielding a response rate of 82.2%. A categorical statistical approach was used to understand consumer's selection for each channel. Besides, binary logistic regression model was used to analyze the factors affecting consumers' channel selection.

Findings

The results show that Chinese wine consumers' main purchasing channels are as follows: supermarket/mall, wine specialty stores, comprehensive e-business flagship stores, comprehensive e-business individual stores, restaurants and short video and live streaming platforms. Estimation results showed that among the 12 influencing factors in 4 categories, consumers' education and some other factors significantly influenced consumers' decision on wine purchasing channels.

Research limitations/implications

Limited by time and experimental conditions, this study did not analyze the trend of wine consumers' purchasing channel selection. Future work would concentrate on multi-year data and conduct longitudinal comparative analysis.

Originality/value

Abstract

Purpose

The purpose of this paper is to develop a common remaining shelf life prediction model that is generally applicable for postharvest table grape using an optimized radial basis function (RBF) neural network to achieve more accurate prediction than the current shelf life (SL) prediction methods.

Design/methodology/approach

First, the final indicators (storage temperature, relative humidity, sensory average score, peel hardness, soluble solids content, weight loss rate, rotting rate, fragmentation rate and color difference) affecting SL were determined by the correlation and significance analysis. Then using the analytic hierarchy process (AHP) to calculate the weight of each indicator and determine the end of SL under different storage conditions. Subsequently, the structure of the RBF network redesigned was 9-11-1. Ultimately, the membership degree of Fuzzy clustering (fuzzy c-means) was adopted to optimize the center and width of the RBF network by using the training data.

Findings

The results show that this method has the highest prediction accuracy compared to the current the kinetic–Arrhenius model, back propagation (BP) network and RBF network. The maximum absolute error is 1.877, the maximum relative error (RE) is 0.184, and the adjusted R2 is 0.911. The prediction accuracy of the kinetic–Arrhenius model is the worst. The RBF network has a better prediction accuracy than the BP network. For robustness, the adjusted R2 are 0.853 and 0.886 of Italian grape and Red Globe grape, respectively, and the fitting degree are the highest among all methods, which proves that the optimized method is applicable for accurate SL prediction of different table grape varieties.

Originality/value

This study not only provides a new way for the prediction of SL of different grape varieties, but also provides a reference for the quality and safety management of table grape during storage. Maybe it has a further research significance for the application of RBF neural network in the SL prediction of other fresh foods.

Abstract

Purpose

The paper aims to understand the cost-benefits, financial performance and relationships of the key actors in the table grape supply chain by using value chain analysis method.

Design/methodology/approach

This study presents the result of analysis on financial performance of key actors in three table grape supply chains and the relationship among them using value chain analysis. The table grape supply chain was analyzed using data collected from a field survey in 5 regions of China. The key actors of these chains were interviewed. The costs, benefits, operational and financial performance of supply chain actors were analyzed.

Findings

The results show that, despite receiving the highest proportion of total net profit and making the highest value creation, vinegrowers are facing fluctuant and uncertain commercial returns due to the production and market risks, fluctuation of farm-gate price and the buyer dominant relationship with wholesalers. Moreover, although it is profitable to all key actors, table grape supply chain still faces several challenges including unorganized and dispersed production systems, power asymmetry and lack of information sharing, all of which are the barriers to the improvement of the whole chain performance and the long term sustainability of this important industry.

Originality/value

This paper not only helps to understand the relationship among the key actors and the critical factors impacting on the whole chain performance, but also offer useful guidance for the policy makers and key actors to achieve further improvement of the table grape supply chain performance and provide valuable implications for the future studies on agriculture products.

Abstract

Purpose

The purpose of this paper is to analyze and identify Chinese consumers’ behavior and preference characters toward table grapes, especially to explore the variance of consumption preference in recent five years.

Design/methodology/approach

Two representative China-wide questionnaire surveys were conducted by face-to-face and online questionnaire survey, respectively, in 2009 and 2014. Comparative study was adopted to dig the changes of consumers’ preferences and habits. ANOVA was adopted to explore the statistically difference among consumers’ behavior and preferences.

Findings

The results indicate that Chinese consumers are rational-motivation-driven grape consumers, they prefer to sweet taste, seedless and medium priced grapes. Safety and quality characters (clean appearance, freshness and taste) were ranked as the most important grape attributes. As a whole, it was found that consumers are more quality-focussed and safety-conscious five years later, so some variances was showed in their purchase habits and preferences, such as the choice of purchase place, attitude to special grapes and willingness to pay to safe and genetically modified grapes.

Originality/value

This research not only indicates some stable preferences of Chinese consumers toward table grape, but also finds out some significant changes in consumers’ behavior before and after five years based on a comparative study in 2009 and 2014.

Abstract

Purpose

Chinese consumers have increased their consumption of grape products in recent years due to recognition of the nutritional value of grapes. At the same time, consumers are paying more attention to food safety because of the occasional occurrence of food safety scares. Based on a survey of consumers in Zhejiang, China, this paper aims to understand and provide information on consumers' perceptions of quality and safety for grape products, purchasing behavior, and willingness to pay (WTP) for grape products.

Design/methodology/approach

This paper presents the results of empirical research. The survey method was a direct (face‐to‐face) interview based on a standardized questionnaire. Consumers' perceptions of the quality and safety of grape products were examined, together with consumers' demographic characteristics.

Findings

The results indicate that quality and safety, rather than price, are considered the most important factors that affect consumers' purchasing decisions for grape products. Consumer's educational level, the average price of grapes and the perception of safety are the main factors that determine consumers' WTP for grape products. As price increases, the consumer's WTP for safe and high quality grapes decreases.

Originality/value

This research provides a chance to understand consumers' demand and WTP for the quality and safety of grape products in Zhejiang, China. Further understanding was gained regarding factors affecting consumers judging grape products, which in turn may influence their purchase decisions. The results also could guide grape growers to supply products that better meet consumers' needs. It is proposed that the Chinese government pay more attention to taking measures to improve the quality and safety of grape products.
