Abstract

Purpose

This study aims to provide a flexible and cost-effective solution of 3D heterogeneous integration for applications such as micro-electro-mechanical system (MEMS) applications and smart sensor systems.

Design/methodology/approach

A novel 3D system-in-package (SiP) based on stacked silicon submount technology was successfully developed and well-demonstrated by the fabrication and assembly process of a selected smart lighting module.

Findings

The stacked module consists of multiple layers of silicon submounts which can be designed and fabricated in parallel. The bonding and interconnecting process is quite simple and does not require complicated equipment. The 3D stacking design offers higher silicon efficiency and miniaturized package form factor. The submount wafer can be assembled and tested at the wafer level, thus reducing the cost and improving the yield.

Research limitations/implications

The embedding design presented in this paper is applicable for modules with limited number of passives. When it comes to cases with more passive devices, new process needs to be developed to achieve fast, inexpensive and reliable assembly.

Originality/value

The presented 3D SiP design is novel for applications such as smart lighting, Internet of Things, MEMS systems, etc.

Abstract

Purpose

This study investigates the potential association between corporate digitization and disclosure quality, and how this relationship is moderated by non-state ownership and institutional environment.

Design/methodology/approach

Drawing on signaling theory and factors that affect disclosure quality, the authors developed a framework to study how corporate digitization is associated with disclosure quality. The proposed framework was empirically tested using a comprehensive analysis that integrated corporate-level data on digitalization, disclosure quality, and ownership structure, with regional-level data on the institutional environment. The authors employed linear panel regression models with fixed effects.

Findings

The authors found that corporate digitization is significantly and positively associated with higher disclosure quality. This positive association is particularly pronounced for non-state-owned enterprises compared to state-owned enterprises. Additionally, an improvement in the institutional environment strengthens the positive relationship between digitization and disclosure quality.

Originality/value

This work contributes to the literature on corporate digitization by empirically investigating its impact on disclosure quality. The study also extends previous research by considering the moderating roles of ownership structure and institutional environment on the digitization-disclosure quality relationship.

Abstract

Purpose

This paper aims to argue for a China transmuting to fast overtake USA in innovation based on the extrapolation of past statistical trend. Case studies in self and co-innovation are provided so that the documentation of the dynamics of knowledge flows and a brain-linguistic explanation is given as to why, in the future, the Chinese are likely to lead in innovation.

Design/methodology/approach

This paper illustrates a multi-method approach in research for Chinese Management Studies. First, the sociological background of China is highlighted (Mao Zedong’s aphorism). Second, insights from OECD patent database are utilized. Third, the use of comparative research and development case-studies: self-innovation (Chinese) and co-innovation (contrasting Japanese versus French cooperation with Chinese). Fourth, is the inter-disciplinarily approach wherein the assimilating of knowledge is related to recent advances in brain research. Fifth, emphasizing the different levels in organizing for innovation: national (China), organizational (SOE), group processes and person-to-person, synapses within individual brains.

Findings

Statistical trend suggests that China is transforming and is on the path toward overtaking the USA in innovation. When will this happen? Using extrapolation as an indication, China may surpass the USA by the 50 per cent mark within the next decade. Insights into the processes of self-innovation and co-innovation are provided. Authors argue for a brain-linguistic explanation (Hebb, 1949) for further understanding why China will eventually lead ceteris paribus innovation, a function of the human brain.

Originality/value

This paper highlights on the basis of statistical trends (using OECD database) a rising, innovative China that is poised to overtake the USA in the near future. A major contribution is in providing insights of interactional processes required to foster innovation: self and co-innovation (comparing Japanese and French). The critical brain-linguistic role as the rationale as to why the Chinese are given a greater, more developed brain power that will eventually surpass the West in innovation.

Abstract

Purpose

The drive shaft and the distribution shaft of a traditional radial piston pump are in a cantilever state. To solve this problem, this paper aims to present a radial piston pump with through shaft driving and valve plate distribution.

Design/methodology/approach

The working principle of the pump is discussed in detail. In this radial piston pump, valve plate distribution parts are designed to distribute oil to the piston chambers, and the distribution shaft is replaced. A bearing is installed between the stator and rotator to reduce the friction. The transmission shaft is supported by two bearings to ensure smooth operation. The support force of the transmission shaft is optimized. In addition, the flow pulsation principle is presented. To accomplish the change, the displacement of the radial piston pump, the proportional control system is designed.

Findings

After completing the machining and assembly of the pump, an experimental study was carried out. The results show that the output flow of the pump is basically the same as the theoretical flow.

Originality/value

The friction between the slipping shoes and the stator is greatly reduced due to the function of rolling bearings. The higher stability of the driveshaft is obtained for the reason of double-sided support. The radial piston pump has a novel structural design in reducing the friction between the shoes and the stator and improving the stability of the transmission shaft.

Abstract

Purpose

Scholars have examined the relationship between sports and urban development and proposed to use sport programs and events as a catalyst to revitalize communities, upgrade urban infrastructure, promote city image, shift economic structure, nurture an active lifestyle, and enhance societal harmony and solidarity. Yet, previous studies were usually focused on mega sport events and were typically conceptual, theoretical and lack of practical applications. This study was designed to attain in-depth understanding on how a specific sport, table tennis, can be systematically organized and utilized to influence urban development through a qualitative research injury.

Design/methodology/approach

This investigation was carried by conducting in-depth interviews of the executive director of the Shanghai Table Tennis Association, on-site observations and comprehensive review of literature. Development of interview questions took into consideration the conceptual framework postulated by Preuss (2007) that contains six structures of urban development through sports. Triangulation analyses were conducted to cross validate the three information sources to generate themes and assertions.

Findings

While the identified practices were consistent with Preuss' (2007) framework, specific management activities earnestly practiced in Shanghai are centered on utilizing cultural and historical heritage, star power, branding strategies, staging tournaments, hallmark events, technical innovation and government relations to achieve the objectives of table tennis as a sport and the objectives of urban development through table tennis.

Originality/value

The findings of this study help fill the void that a theory usually cannot specify, namely, detailed, unambiguous practices. While table tennis may be a viewed as a small sport in many parts of the world, it has a strong, unprecedented historical heritage in Shanghai. This city has made a prudent choice and investment in this sport, which has proved to be effective. Other cities in the world should look into their own social, cultural and historical heritage and develop sport strategies, operations and programs accordingly.

Purpose

The purpose of this paper is to summarize the advances in grey system theory research and various application achievements in science and engineering. At the same time, it commemorates the 40th anniversary of the birth of grey system theory and the 10th anniversary of Grey Systems–Theory and Application.

Design/methodology/approach

Firstly, the innovations of theoretical research in grey system theory were summarized and some of the widely recognized new results are briefly described. By searching and combing the research results of grey system theory in China national knowledge infrastructure (CNKI) database and Web of Science by Institute for Scientific Information (ISI), this paper shows the rapid development trend of grey system theory in the past 40 years, and the successful applications of grey system theory in the fields of social sciences, natural sciences and engineering technologies.

Findings

More than 227 thousands literature were found by input 10 phrases such as grey system, grey number and sequence operator etc. in CNKI database. After entering the new century, the number of grey system papers included in CNKI database is increasing rapidly. Since 2008, more than 10 thousands papers have been included per year and more than 15 thousands papers have been included per year since 2014. Grey system method and model are widely used in physics, chemistry, biology and other fields of natural science, as well as transportation, electric power, machinery and other fields of engineering technology, and a large number of valuable results have been achieved.

Practical implications

Abstract

Purpose

This paper aims to identify how house price affects household consumption.

Design/methodology/approach

The authors use a micro-level data set that tracks the house price and consumption of a vast number of households over a period of four years. OLS regression is the main econometric method.

Findings

The authors document robust evidence that an increase in house prices stimulates household consumption, regardless of whether a household owns or rents. Moreover, the authors find that both acquiring and losing homeownership negatively affects household consumption. Further investigation suggests significant regional heterogeneity in the relationship between house prices and household consumption.

Originality/value

This is one of the first studies examining the relationship between house price and household consumption in China using micro-level data. Given the uniqueness of the Chinese housing market and China’s fast-growing consumption rate, the study contributes new evidence to the long-lasting debate.

Abstract

Purpose

To examine “universal service” as a policy objective in post‐WTO accession Chinese telecommunications and analyze the challenges of the Chinese telecommunications system in defining and promoting public service ethos in a country that is marked by staggering disparities.

Design/methodology/approach

A range of media, academic, industry, and policy discourses on “universal service” and a broader notion of “public service,” together with recent government efforts in promoting “universal service,” are examined and assessed to develop an analysis of the uneven nature of China's telecommunications development and reveal the dynamics of “universal service” policy formation, as well as the impetuses and impediments in developing any notion of public service telecommunications in China.

Findings

Public service issues in China need to be situated within a continuing process of uneven development which comprises dimensions other than residential telephone access. Although the ultimate policy goal appears to develop a nationally accessible telecommunications infrastructure as the basis of a unified national economy, this overall objective is beset by conflicts and contingent on the dynamics of elite and popular struggles over and beyond telecommunications development. Despite the spectacular expansion in telephone access, pragmatic concessions to dominant power groups, rather than a principled commitment to “universal service,” let alone efforts to define the social functions of telecommunications in more democratic ways, have shaped the development of China's telecommunications.

Originality/value

The development of China's telecommunications infrastructure offers lessons both as to the likelihood of successfully establishing an integrated national economy, and the role of public service in that context. However, the Chinese telecommunications policy field remains extremely fluid.
