The purpose of this paper is to investigate how information and communication technology (ICT) impacts firm performance, by changing the information processing ability of a firm.

It takes the firm as information processing unit to coordinate production in an industry with two‐stage production and demand uncertainty. ICT is assumed to improve the information processing ability. It models that, conditional on the structure of markets described by level of uncertainty, a firm with information processing ability comes into being endogenously from market‐coordinated production, with profit generated.

It is argued that the profit of the firm depends on both the structure of markets, and the firm's information processing ability. The improving information processing ability increases firm profitability as long as market‐coordinated production persists elsewhere. However, when the improving information processing ability enables enough firms to compete with no market‐coordinated production left, it decreases profitability of all firms. Finally, case studies on the wholesale and retail industry and the finance and insurance industry of ten OECD countries presents consistent evidence that ICT does not necessarily bring better performance.

This paper is an innovation based on several streams of literature to model a firm with the consideration of specialization, demand uncertainty, and information processing ability. It thus provides a different perspective on how ICT contributes to firm performance. It theoretically and empirically shows that such contributions are conditional on market structure of a certain industry.

The purpose of this paper is to provide the historical background of genealogical records and analyze the value of Chinese genealogical research through the study of names and genealogical resources.

The paper examines the historical evolution and value of Chinese genealogical records, with the focus on researching the Islamic Chinese names used by the people living in Guilin. The highlight of this paper includes the analysis and evolution of the Islamic Chinese names commonly adopted by the local people in Guilin. It concludes with the recommendations on emphasizing and making the best use of genealogical records to enhance the research value of Chinese overseas studies.

The paper covers the history of Islam and describes how the religion was introduced into China, as well as Muslims' ethnicity and identity. It also places focus on the importance of building a research collection in Asian history and Chinese genealogy.

This research study has a strong subject focus on Chinese genealogy, Asian history, and Islamic Chinese surnames. It is a narrow field that few researchers have delved into.

The results of this study will assist students, researchers, and the general public in tracing the origin of their surnames and developing their interest in the social and historical value of Chinese local history and genealogies.

The study of Chinese surnames is, by itself, a particular field for researching the social and political implications of contemporary Chinese society during the time the family members lived.

Very little research has been done in the area of Chinese local history and genealogy. The paper would be of value to researchers such as historians, sociologists, ethnologists and archaeologists, as well as students and anyone interested in researching a surname origin, its history and evolution.
