The COVID-19 pandemic may have had a negative impact on dairy consumption trends. Many dairy products are perishable and have relatively high income elasticity, causing their susceptibility to market fluctuations in general, including those specifically caused by the pandemic. However, the pandemic has also brought some other prospective possibilities. For example, during the pandemic, people paid more attention to nutrition and health issues and increased the number of meals prepared and eaten at home. In consideration of the particular circumstances during the pandemic, the Chinese government issued several policies to promote the population’s dairy consumption, and the Chinese dairy cattle sector actively implemented the policy of “guarantee price, quality, and supply”. These factors may have caused the Chinese population to increase their consumption of dairy products during the pandemic. Before the pandemic, the consumption of dairy products in the Chinese population showed an overall upward trend. The question addressed in this study is how has COVID-19 affected dairy consumption trends during the pandemic? This study uses accounting data from the Chinese dairy cattle sector to empirically analyze the impact of the COVID-19 pandemic on dairy consumption trends through economic theories and translog revenue function. Our study found that COVID-19 increased consumers’ consumption of dairy products in China, but those people experiencing poverty may still have experienced inadequate dairy intake. This study has contributed to the body of work in this area in the literature and provides response strategies for the dairy cattle sector and the authorities.

This paper specifies a trans-log revenue function to estimate the relationship between service revenue outputs and three key human capital inputs, including formal education, work experience, and professional training. Using a Taiwanese pooled cross-sectional sample of 22,875 observations over the period 1992-2021, we divide the total sample into international and non-international audit firms based on their total audit revenues. We find that the average partial effects (APEs) on revenues are much higher for international than for non-international audit firms, suggesting that audit firm size affects audit firms’ financial performance. We also find that investments in both formal education and work experience significantly contribute to the growth of service revenues (but if such investments are beyond the optimal level, they may contribute to the reduction of revenues) and that such growth is much larger for international than for non-international audit firms. Although we find that, in our statistical analysis, professional training contributes to the reduction of service revenues, our graphical analysis justifies this intriguing finding, which is attributed to a lagged return on professional training investments. In theory, human capital suggests that professional training is a needed process to raise future service revenues. Overall, our findings shed light on the APEs of human capital inputs on revenue generation and have practical implications for regulators and practitioners to understand how and to what extent human capital can make a positive contribution to the growth of audit firms’ revenues.

Since the outbreak of the COVID-19 pandemic, the rapid spread of COVID-19 around the world has become one of the main focuses of concern in almost every country, and governments have taken numerous measures to prevent/mitigate the spread of the disease. As an essential social determinant, COVID-19 has significantly impacted consumers’ food consumption behavior and healthy eating habits/behaviors. The purpose of this study is to analyze the impact of COVID-19 on food consumption behavior, and the main goal was to assess the possible problems (such as food waste and weight gain) caused by changes in food consumption behavior during the pandemic. Based on the accounting data of Chinese enterprises found in the China Stock Market and Accounting Research (CSMAR) database, this study uses economic theory and the translog function to conduct an average partial effect (APE) analysis of the pandemic, and finds that the COVID-19 pandemic has increased Chinese people’s overall food consumption, and the consumption of food from large food enterprises has increased even more (APE = 0.11 vs. APE = 0.31). This study suggests that food waste and weight gain in the Chinese population may be more severe during the pandemic, and it is necessary to enhance food management and weight management through multiple pathways.

The General Office of the State Council of China promulgated the National Nutrition Program 2017–2030 in 2017 to guide the people to improve their food supply and nutritional intake. This study uses qualitative and quantitative information which are analyzed to estimate the change in people’s food purchases following the implementation of the National Nutrition Program 2017–2030, and puts forward measures that should be taken by the competent authorities and stakeholders. We use the translog revenue function of the food industry, and based on the data of listed companies of Chinese food enterprises from 2015 to 2020, and this study find that the National Nutrition Program 2017–2030 has had a positive impact on people’s food purchases, and the impact is more obvious in people’s food purchases from large food manufacturers. Finally, we also provide regulators with public policy implications, and provide food manufacturers with development suggestions.

This study attempted to explore the competitive advantage strategies of the medical consumables industry (MCI) from the perspectives of human resources, research and development (R&D) and the industry life cycle. As one of the essential branches of modern medical device industry, the MCI has developed rapidly in recent years as global demand for medical consumables has shown continual growth, but it also faces market uncertainty. This study took Taiwan’s small/medium medical consumables enterprises (SMMCEs) as a sample, and used the translog revenue function to study the competitive advantage of the MCI through human resource and R&D investment strategies and the stage characteristics of the industry life cycle curve. The results showed that the various human resources and R&D expenses of the small/medium medical consumables industry (SMMCI) can interact with each other to influence total revenue and that the SMMCI needs more varied types of human resources to enhance its competitive advantage. The total revenue of the SMMCI decreased as education inputs rose, but it increased along with increases in the number of employee and R&D inputs. Observed from the life cycle curve of the SMMCI, total revenue increased rapidly during the startup and growth stages, increased slowly during the maturity stage, and decreased during the decline stage. Finally, we put forward competitive advantage strategies and management suggestions for medical consumables enterprises (MCEs). We are the first to document the life cycle curve and competitive advantage strategies of the MCI, thereby contributing to the related literature.

Taiwan’s Financial Supervisory Commission of the Executive Yuan promulgated the fully amended Certified Public Accountant Act in 2007, which directly led to significant changes in accounting law. From the perspective of the economic theory of law, this study investigates the amendment of the Certified Public Accountant Act resulting in an increase or decrease in the overall revenue and different revenue shares of accounting firms, and puts forward measures that should be taken by accounting firms and stakeholders. We focus on large accounting firms and divide the sample period into before and after 2008. This study uses the translog revenue function and revenue share functions of the public accounting industry, and based on the 1989–2017 Survey Report of Audit Firms in Taiwan, and we find that the amendment of the Certified Public Accountant Act has had a positive effect on overall revenue, increasing overall revenue and the overall management advisory services shares, and in reducing the overall accounting and auditing shares and tax services shares of large accounting firms. Additional analyses provide regulators with public policy implications and provide accounting firms with managerial information.

This study examines the association between professional training, higher academic qualifications (educational levels) and operating performance of audit firms in Taiwan. We particularly focus on the curvilinear effects of higher academic qualifications on operating performance. We group the total sample into three categories: national, regional and local audit firms. Based on the theoretical framework in industrial economics, we establish a cross-sectional multiple regression equation to test our hypotheses. Both higher academic qualifications and professional training are positively related to the operating performance of audit firms. Professional training moderates the relation between higher academic qualifications and operating performance. Higher academic qualifications exhibit a curvilinear effect on operating performance with a reverse U-shaped relation for the national audit firms and a U-shaped relation for both regional and local audit firms. Due to data unavailability, some factors affecting the audit quality and operating performance are not included in our analysis, such as auditor teamwork, internal control system, operating policies and auditing procedures of audit firms. The findings that higher academic qualifications are positively associated with the operating performance of audit firms justify the educational policy of establishing institutes or graduate schools in accounting over the past two decades. Furthermore, audit firms skillfully exploit employees with higher academic qualifications to improve their operating performance. We are the first to document the moderating effects of professional training and the curvilinear association between higher academic qualifications and operating performance, contributing knowledge to related literature.
