Abstract

Purpose

The purpose of this paper is to provide further insight into Chinese wine consumers’ preference, grasp the regional sensory preference differences of China and build up a predictive model for wine consumers’ sensory preferences.

Design/methodology/approach

The study involved 3,421 Chinese wine consumers in the survey. Classified statistics were conducted to excavate regional differences of wine consumers’ sensory preferences. By analyzing influencing factors, prediction models for consumers’ sensory attribute preferences were constructed on the basis of multivariate disorder logistic regression method.

Findings

Empirical research showed that the wine with the following sensory attributes was the most preferred by Chinese consumers: dry red, refreshing and soft taste, still type, moderate aroma degree and mellow aroma, and sweet wine was also popular. Consumers’ preference varied from region to region. The proposed predicting method of the study realized more than 70 percent accuracy when conducting prediction for color, sweetness, aroma type and flavor preferences.

Social implications

By shedding light on the latest sensory attribute preferences of Chinese wine consumers, this study will help wine industry participants conduct market segmentation based on the diversification of consumers’ preferences. The wine enterprises can gain guidance from the results to conduct market positioning, adjust strategies and provide specific production for target wine consumers.

Originality/value

Based on the actual situation of Chinese wine market, this study defines sensory attribute indexes of wine from the perspective of wine consumers and presents the most recent comprehensive research on the sensory preferences of Chinese wine consumers through a nationwide survey.

Abstract

Purpose

The purpose of this paper is twofold. First, the authors investigate a firm’s decision to provide a CSR report, and if so, whether to have the report assured and to seek higher quality assurance as reflected through the choices of the scope of the assurance and type of assurer, Big 4 accounting firm vs specialist consultant. Second, the authors investigate the impact of voluntary assurance of CSR reports, assurance scope and type of assurer on the likelihood of inclusion in the DJSI and on market valuation.

Design/methodology/approach

The study’s sample consists of 17,050 firm-year observations from 40 countries with CSR reports available from Corporate Register and ESG metrics available from ASSET4 over the period 2009–2015. The study first empirically examines the associations between CSR commitment and each of CSR report provision, CSR report assurance, assurance scope and type of assurer. It then examines that association between both inclusion in the DJSI and market valuation with each of CSR report assurance, assurance scope and type of assurer, using inclusion in the DJSI as an objective measure of a firm’s reputation for sustainability given its recognition as a leading indicator for corporate sustainability and market valuation as a reflection of the broader set of capital market participants.

Findings

The authors establish two key findings consistent with the predictions of signaling theory. First, we show that high CSR commitment firms are more likely to: provide standalone CSR reports; obtain assurance; obtain assurance from a Big 4 accounting firm; and, adopt higher assurance scope. Second, the authors find that both CSR report assurance and assurance scope increase the likelihood of inclusion in the DJSI, but that the type of assurance provider does not. Alternatively, the authors find that capital market participants appear to value the provision of a CSR report only when it is assured by a Big 4 accounting firm.

Originality/value

The results in the existing literature exploring the capital market benefits to CSR Assurance have been mixed. Firms that voluntarily obtain CSR Assurance incur a cost in doing so and must perceive a net benefit from obtaining such assurance. Despite the limited guidance currently provided by existing CSR standards, we establish the existence of benefits to obtaining CSR Assurance in terms of enhanced likelihood of DJSI inclusion and, more generally, enhanced market valuation. The discussions with DJSI analysts indicate that CSR assurance does enhance the perceived reliability of CSR data, thus improving user confidence.

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

It has been widely documented that investors and analysts underreact to information in past earnings changes, a fundamental performance indicator. The purpose of this paper is to examine whether managers’ voluntary disclosure efficiently incorporates information in past earnings changes, whether analysts recognize and fully anticipate the potential inefficiency in management forecasts and whether managers’ potential forecasting inefficiency entirely results from intentional disclosure strategies or at least partly reflects managers’ unintentional information processing biases.

Design/methodology/approach

Archival data were used to empirically test the relation between management earnings forecast errors and past earnings changes.

Findings

Results show that managers underreact to past earnings changes when projecting future earnings and analysts recognize, but fail to fully anticipate, the predictable bias associated with past earnings changes in management forecasts. Moreover, analysts appear to underreact more to past earnings changes when management forecasts exhibit greater underestimation of earnings change persistence. Further analyses suggest that the underestimation of earnings change persistence is at least partly attributable to managers’ unintentional information processing bias.

Originality/value

This study contributes to the voluntary disclosure literature by demonstrating the limitation in the informational value of management forecasts. The findings indicate that the effectiveness of voluntary disclosure in mitigating market mispricing is inherently limited by the inefficiency in management forecasts. This study can help market participants to better use management forecasts to form more accurate earnings expectations. Moreover, our evidence suggests a managerial information processing bias with respect to past earnings changes, which may affect managers' operational, investment or financing decisions.

Abstract

This chapter studies banks’ loan pricing behavior in mainland China during 2003–2013 by applying panel regressions to firm-level loan data and the estimated default likelihood for listed companies. The authors find that with the progress of market-oriented financial reforms, banks generally require compensation for their exposure to borrowers’ default risks. It is even more so if the borrower is a non-state-owned enterprise (non-SOE), mainly due to the pricing behavior of the Big Four banks. Bank lending rates are shown to be less sensitive to the default risks of state-owned enterprises (SOEs). Our results also reveal that banks priced in firm default risks before 2008 financial crisis, but not necessarily so after the crisis. As for industries, we find that after the 2008 Global Financial Crisis, the real estate sector and other government-supported industries tended to enjoy better terms on loan pricing in terms of default risks. We believe the main reason is that the government stimulus policies tilted toward those industries that have played crucial roles in China’s economic growth.

Abstract

Purpose

This empirical study aims to test the impact of four types of entrepreneurial context on the growth and success rates of new ventures in China and related the findings to the theory and practice of entrepreneurship dating back 2,500 years to ancient China.

Design/methodology/approach

After describing the business guidelines given by Fan Li, an entrepreneurial merchant selling Chinese medicines in ancient times, a conceptual framework was extracted as the basis for a discussion of the relationship between entrepreneurial context and entrepreneurial activity. Entrepreneurial context was conceptualized as being composed of family, social, business and institutional components. Five hypotheses about the influence of these different context variables on entrepreneurial activities were developed. From data compiled from the sampling of 239 business entrepreneurs in Beijing, a hierarchical regression was formed and the hypotheses tested.

Findings

The impact of entrepreneurial context on entrepreneurial activity can be divided into two layers, internal factors (e.g. family context) which are similar to “yin” (?) in the traditional Chinese philosophy while external factors (e.g. business, social and institutional contexts) were like “yang” (?). The two factors play different roles in entrepreneurial activities, while different contexts mediate and moderate each other in complex ways.

Research limitations/implications

Research limitations pertain to the size and locale of the sample. A larger sample that involved subjects from different regions would facilitate a wider understanding of the effects of entrepreneurial context upon the entrepreneurial process.

Originality/value

The theory of entrepreneurial context is in its beginning stages, and the paper completed a systematic study of entrepreneurial context through theoretical model building using large-sample empirical research. In addition, the paper is the first ever to relate the theory and practice of entrepreneurship back 2,500 years. Through a multi-research methodology, the study clearly shows the critical importance of integrating Chinese history into the development of management theory.

Abstract

Purpose

The purpose of this study is to construct a Chinese information science resource ontology and to explore a new method for semiautomatic ontology construction.

Design/methodology/approach

More than 8,290 articles indexed in the Chinese Social Science Citation Index (CSSCI), covering the years 2001 to 2010, were included in this study. Statistical analysis, co-occurrence analysis, and semantic similarity methods were applied to the selected articles. The ontology was built using existing construction principles and methods, as well as categories and hierarchy definitions based on CSSCI indexing fields.

Findings

Seven categories were found to be relevant for the Chinese information science resource ontology, which, in this study, consists of a three-tier architecture, 78,291 instances, and 182,109 pairs of semantic relations. These results indicate the following: further improvements are required in ontology construction methods; resource ontology is a breakthrough concept in ontology studies; the combination of semantic similarities and co-occurrence analysis can quantitatively describe relationships between concepts.

Originality/value

This study pioneers the resource ontology concept. It is one of the first to combine informetric methods with semantic similarity to reveal deep relationships in textual data.

Abstract

Purpose

The purpose of this paper is to discuss nationalistic education in Hong Kong from a cultural perspective. It highlights the challenges faced by the Hong Kong Government and the growing antagonism and mistrust between the young generation and the government. The paper reviews the cultural policies adopted by the Western Zhou, Han and Tang dynasties in ancient China.

Design/methodology/approach

This paper adopts a historical approach by reviewing the policies in music and culture in the Chinese history and argues for the adoption of a soft approach to nationalistic education in Hong Kong.

Findings

Results show that being inclusive toward diverse cultures, trusting and valuing people’s voices and accepting differences of opinion are effective policies that were adopted by the respective dynasties. The results shed light on the possibility of nurturing nationalism through education in music and culture.

Research limitations/implications

The historical examples mentioned in this paper are only selected periods of the Chinese history. Thus, the survey could not be taken as a comprehensive review.

Practical implications

This paper reviews the policies concerning music and culture in ancient China and argues for transferring the soft approach of predecessors toward these subjects as part of the nationalistic education of Hong Kong.

Social implications

The results shown should be considered seriously by the Hong Kong Government as an effective substitute policy for the past stringent approach of implementing national education in Hong Kong. Nationalistic education focusing on music and culture is a common root for all Chinese and should be used in future to build up trust and common values between China and Hong Kong.

Originality/value

The originality of this research lies in its dealing with nationalism and national education, recommending a soft approach to education viewed through the prisms of music and culture.

Abstract

In this paper I investigate the nature of the differential in poverty by ethnicity in rural China using data from the Chinese Household Income Project in 2002. For that, I compare observed poverty with that in a counterfactual distribution in which ethnic minorities are given a set of relevant village and household characteristics of the Han majority. In particular, I investigate the importance of the location of minorities in explaining their higher poverty levels. The ethnic poverty differential does not change after equalizing the distribution of the population by geographical region (unless we use a higher poverty line). However, it is reduced after equalizing other locational characteristics of minorities (such as them living in less developed and mountainous areas), their larger number of children, their low education, and their fewer skilled non-agriculture workers. Finally, the ethnic per capita (log) income differential is shown to be higher for higher percentiles, with an increasing role of the geographical region as the main driver of these higher differentials.
