The current paper's goal is to examine the productivity of the closed banking sector evidenced from Ethiopia. In addition, the inclusion of intangibles on productivity was examined in the current paper.

First, the standard Malmquist Productivity Index (MPI) was employed for 13 commercial banks for both stages. Second, by excluding the state-owned commercial bank, the analysis employed a bootstrapped MPI for the robust and comprehensive conclusion. Furthermore, from 2010 to 2019, the fixed effect Ordinary Least Square (OLS) regression with balanced panel data was used.

The standard MPI in both stages shows that the productivity of Ethiopian commercial banks is declining. The technological shock was the main reason for the loss. The catch-up in both stages scored above unity, mainly due to the pure efficiency change. Besides, when combined with tangible resources, the inclusion of resource-based view (RBV) proxy variables reduces technological shock regress and ultimately improves productivity change. The bootstrapped MPI also reveals that technological shock is the primary source of the productivity decline. However, efficiency change also contributes to the productivity decline based on this estimation.

Future research could examine the more extensive productivity analysis by considering the primary sources of data collections for resource-based variables.

According to the study's results, banking regulatory authorities and bank management, including the shareholders, should continue to invest in cutting-edge technology to improve the productivity of the banking sector.

This is the first comprehensive study of productivity for Ethiopian commercial banks based on the standard MPI, bootstrapped MPI, and OLS by incorporating all resources into the analysis.

The purpose of the paper is to construct a model that considers video purchase and then identifies the logical relationships implied by the parameters to explore video platform operation mechanisms.

The authors analyzed the video platform system using a mathematical modeling approach and numerical optimization techniques. Through pricing decisions, the authors obtained equilibrium results for the profitability of the video platforms and analyzed the favorable market factors. The authors then extended the model by analyzing the competitive strategies of the two video platforms in the market.

The authors find that advertiser profitability, ad nuisance, video sensitivity and video creator network effects are important factors influencing the pricing strategy of video platforms. During positive market conditions, video platforms tend to lower their prices until they absorb enough users. As market conditions change, the price adjustment strategies of video platforms are affected by parameter changes and inter-parameter relationships.

The study considers the network effects of video creators, which provides a realistic reference for scholars and managers. In addition, the authors consider the bargaining power of platforms when purchasing content. The authors provide a fresh perspective for scholars while filling a gap in the field as video platforms can acquire a portion of the content on the market by setting a purchase price.

The study aims to map the intellectual structure of business ethics studies by analyzing 17,246 citations of 225 papers published in Business Ethics Quarterly (BEQ) in the year between 2005 and 2014. Specifically, the purpose of the study is to describe the current state of BEQ, identify the most influential journals and works, identify the key themes of business ethics studies during 2005-2014 and, at the same time, report the changes in themes by making a comparison between two time periods – 2005-2009 and 2010-2014.

First, the study presents the information of the authors, institutions and countries that contribute to BEQ with a statistical analysis. Second, the study identifies the most cited journals and works in BEQ during 2005-2014 with a citation analysis. Third, the study identifies the key research themes in business ethics studies with a co-citation analysis. With the help of factor and social network analysis (NA), the study groups the research themes and maps their links.

First, the statistical results show that many well-known researchers from famous US institutions publishing in BEQ. Second, the citation analysis results show that quite a few journals become mature gradually in business ethics domain. Besides, most of the influential works are normative and theoretical. Third, the co-citation results indicate that “stakeholder management” and “corporate social responsibility” (CSR) are two main themes in business ethics studies in the past decade. Specifically, “stakeholder management” attracts the most research interests in both two sub-time periods. In addition, compared with the pure studies on CSR during 2005-2009, increasing researchers are keen on the theme of “political CSR under globalization” in the second five years. Meanwhile, other focus like “society, state and business ethics” earns a certain degree of attention in the time window 2005-2009. And “accountability in MNCs” and “political philosophy” are the new concerns in the year between 2010 and 2014.

The study confirms BEQ’s leadership role in business ethics domain. And, it further proves that business ethics has evolved as an independent discipline. It also helps the researchers to have a concise knowledge of the main contents and key points of business ethics research. Methodologically, co-citation analysis combined with factor and NA provides clear results and visualized figures which can be understood easily by the researchers and practitioners.

In an attempt to satisfy the desire to become a global economic leader, China is working on a series of ambitious deals with several countries. As a major country in a region considered as an emerging market, the immense infrastructure gap that is curtailing trade and accessibility for economic growth has led to major changes in economic policy. The past few decades have seen China invest billions of dollars not only in the developing countries of Africa and Asia but also in other world economic giants of Europe and the USA. China has embarked on a rigorous global effort to close the infrastructure gap through the Belt and Road Initiative (BRI) in partnership with multilateral development banks. China’s BRI brings together several countries in East Asia and the Eurasian mainland into close proximity with China, thereby promoting inland trade between the countries. The investments in this project are estimated to reach US$1tn over a span of ten years. However, the volume of outward foreign direct investments (OFDI) from China to the host countries is determined by several factors. Several previous researchers have studied various issues affecting the business activities of China and the given countries. First, the cultural organization, policy approaches and objectives of China as a country create trade barriers with countries involved in the BRI plan. This paper aims to provide a comparative overview of how the institutional distance of the Belt and Road countries from China affects their sustainable development.

Data on the nature, success and challenges of the BRI (such as the volume of bilateral trade and OFDIs and its financial implications) were extracted from various published studies. The impact of cultural distance and internationalization of the BRI enterprise was analyzed through a comparative research methodology.

A significant relationship exists between institutional distance and sustainable development of the Belt and Road countries. However, the barriers – for example, inhospitable culture and regulations for organizations in participating countries – could become pillars of success once resolved.

Previous studies lacked a standard framework to investigate how institutional distance is related to China’s outbound trade with the Belt and Road countries. The comparative analysis methodology adopted in this study fills this gap.

Soil nutrient management and fertilizer use by farmers are important for sustainable grain production. The authors examined the effect of an experimental agricultural extension program, the science and technology backyard, in promoting sustainable soil nutrient management in the North China Plain (NCP). The science and technology backyard integrates farmer field schools, field demonstrations, and case-to-case counselling to promote sustainable farming practices among rural smallholders.

The authors conducted a large-scale household survey of more than 2,000 rural smallholders. The authors used a multivariate regression analysis as the benchmark to assess the effect of the science-and-technology backyard on smallholder soil nutrient management. Furthermore, the authors used coarse exact matching (CEM) methods to control for potential bias due to self-selection and the (endogenous) switching regression approach as the main empirical analysis.

The results show that the science-and-technology backyard program increased smallholders' wheat yield by approximately 0.23 standard deviation; however, no significant increase in maize yield was observed. Regarding soil nutrient use efficiency, the authors found a significant improvement in smallholders' phosphorus and potassium use efficiencies for both wheat and maize production, and a significant improvement in nitrogen use efficiency for wheat production, but no significant improvement of nitrogen use efficiency for maize production.

This study evaluated a novel participatory agricultural extension model to improve soil nutrient management practices among smallholders. The integration of agronomists' scientific knowledge and smallholders' local contextual experiences could be an effective way to improve farmers' soil nutrient management. This study provides the first quantitative estimates based on rigorous impact assessment methods of this novel extension approach in rural China.

This paper aims to investigate the influence of the contact status between the seal ring and its support on the seal performance in hydrostatic mechanical face seal.

A thermal fluid-solid interaction (TFSI) model of hydrostatic mechanical face seal is further developed, in which the multi-body contacts between components are particularly given more attention. The numerical models of the flow field and complete seal assemblies are developed. A specific energy equation is obtained to simplify the calculation of film temperature. Based on the mechanism for the continuity condition of the physical quantities at the fluid–solid interface, the TFSI model uses an on-line iterative coupling method.

The contact status between seal ring and its support affects the seal performance significantly. The rotating ring and the stationary ring contribute differently because of the contact status difference.

The contact status between the seal ring and the ring seat is key to gain an insight into the performance of the hydrostatic mechanical face seal thus provides guidance for mechanical seal design.

The purpose of this paper is to find a solution of laminar liquid flow in asymmetric narrow channels. In many cases, an intuitive solution is much more useful and necessary for engineering applications, although numerical solutions can be obtained.

The Navier‐Stokes equations of laminar liquid flow in asymmetric narrow channels are simplified based on geometric characteristics of narrow channels, physical characteristics of liquid and boundary conditions. The simplified Navier‐Stokes equations are solved theoretically. Verification of the obtained results is carried out based on comparing with the Jeffery‐Hamel flow, which is an exact solution of liquid flow in convergent or divergent channels proposed by Jeffery.

This paper proposed an intuitive solution of laminar liquid flow in asymmetric narrow channels. Obtained results show that the solution can provide a fairly precise flowrate, when a ratio between the width of the channel and the curvature of the boundary of the asymmetry channel is smaller than 0.2936/Re. Furthermore, the obtained solution of pressure distribution along the channel shows high enough accuracy, even though the Reynolds number reaches to higher than 105.

Because the authors assumed the width of the channel is far smaller than the curvature of the boundary of the asymmetric channel, the obtained results could only fit finite cases. Because the Navier‐Stocks equations were finally simplified into one‐dimensional, it is impossible to forecast separation flows; so the obtained results will fail when the Re number is too big. However, experiments should be carried out further to verify these problems.

This paper proposes an intuitive solution of laminar liquid flow in asymmetric narrow channels, including the pressure distribution along the channel.

Currently, most research studies focus on ownership reforms and governance reforms, while only a few research studies focus on management system innovations. Based on an evolution of state-owned enterprises’ (SOEs) performance appraisal systems, this paper investigates the influence of performance appraisal system on earnings management.

Using a natural experiment that central government-owned enterprises (CGOEs) carried out economic value-added performance appraisal (EVA-PA) in 2010, the authors adapt difference-in-difference method to analyze the relationship between EVA-PA and earnings management choice. Furthermore, the authors consider the situation which contained financial status, separation between decision-making rights and decision-control rights, separation between ownership and control and industrial characteristics.

The research finds that after carrying out EVA-PA, CGOEs prefer accrual-based earnings management to real earnings management, and there is substitution effect between the two types of earnings management. Moreover, further research studies reveal that enterprises suffering losses in the previous year and featuring higher separation between decision-making rights and decision-control rights and higher separation between ownership and control have stronger earnings management motive under EVA-PA. In contrast, enterprises achieving satisfactory financial performance in the previous year and engaging in businesses within protective industry have weaker earnings management motive under EVA-PA. After the implementation of EVA-PA, accrual-based earnings management and real earnings management both impair operating performances of CGOEs.

Theoretically, this paper enriches research studies on earnings management from the perspective of incentive mechanism and expands research studies on economic consequences of EVA-PA. In addition, it validates the relationship between the two types of earnings management. As an important mechanism of corporate management and control, performance appraisal system is an important part for establishing ownership management system and improving internal management system of SOEs.

This paper aims to examine the attractiveness of the Tong Ren Tang (TRT) as a Chinese corporate heritage tourism brand and consider the significance of TRT for Chinese national identity. The study considers the saliency of Balmer’s augmented role identity notion vis-à-vis corporate heritage institutions/corporate brands. Insights are made from and for corporate heritage, heritage tourism and national identity literature.

A conceptual model comprising five hypotheses was developed and this informed a survey-based questionnaire administered to domestic tourists/customers visiting Tong Ren Tang’s flagship shop in Beijing.

The attractiveness to domestic Chinese tourists/customers of the TRT corporate heritage tourism brand was found to be attributable to its multiple role identities: national, corporate, temporal, familial and imperial. As such, this study lends credence to Balmer’s augmented role identity notion. Chinese domestic tourists/customers – as members of an ethnic Chinese community – in visiting TRT not only consume an extant corporate heritage by tangible and intangible means but can also be seen to express, and reaffirm, their sense of Chinese national identity.

For TRT’s managers, there should be an appreciation that the attractiveness of TRT as a corporate heritage tourism brand rests not only on what it sells but also in what it symbolises in national and cultural terms. This finding is applicable to the managers of many other corporate heritage/corporate heritage tourism brands.

Adopting a primordial perspective, the TRT pharmacy was found to be of singular significance to China’s national identity. Traditional Chinese Medicine, Confucian and Daoist religious/philosophical and China’s erstwhile Imperial polity are significant and enduring precepts of Chinese national identity. As such the TRT flagship shop/brand is of singular importance, as China has eviscerated much of its cultural heritage – particularly in relation to its corporate heritage brands.

This is the first empirical study to focus on corporate heritage tourism brands and one of the first studies to examine a Chinese corporate heritage/corporate heritage tourism brand. Also significant in focussing on the TRT corporate heritage brand. Established in 1669, TRT’s history spans five centuries: a corporate provenance which is exceptional within the People’s Republic of China. The study links the corporate brand notion with the nascent corporate heritage brand domain and the established area of heritage tourism.
