Performance was measured by Marketability in the first stage, and Profitability in the second stage. In addition, this paper uses the Tobit regression model to examine factors that significantly influence managerial efficiency. Nine variables were employed to examine the model. The results revealed that marketability can be explained by; percentage of outer servers, number of branches, premium investment percentage and corporate image, while profitability can be explained by market share, percentage of premium reserved and corporate image. Moreover, the entire industry can be partitioned into four clusters based on marketability and profitability of a company. Effective management strategies need to be developed specially for of the four clusters of non-life insurance companies. It is hoped this study can provide useful information for managers of non-insurance companies in the future. Introduction As economies become more liberalized, many countries in Asia have gradually removed regulatory controls and opened up access to their insurance markets. There are many opportunities for insurance companies in Asia, but it is still a region undergoing change in terms of regulatory control, although this does vary from country to country. Taiwan's non-life insurance market was originally an oligopoly. In year 1982, two American non-life insurance companies were permitted to establish branches in Taiwan; in 1992, permission was granted to locals and eventually access to the non-life insurance market was fully opened to the public in 1994. Up until the end of 2002, there were 24 non-life insurance companies in Taiwan, 17 of them were local companies and 7 were foreign ones. Though the open access of market brought good business opportunities, it also introduced more competition that has prompted several companies to close down or to be merged. Facing a highly competitive environment, the formulation of competition strategy, strengthening of corporate operations and upgrading of the quality of service have become essential for survival. In formulating competition strategies, one major problem is the measurement of management performance in the industry, prior to an assessment of advantages and disadvantages. Another problem encountered the determination of factors that affect managerial efficiency. This paper uses the two-stage data envelopment analysis (DEA), which was first used by Seiford and Zhu (1999), using multiple inputs and outputs to measure the relative managerial efficiency of 24 non-life insurance companies in Taiwan. Marketability was measured in the first stage while profitability was measured in the second stage. According to the results of the two-stage DEA, this paper will further analyze the strengths and weakness of non-life insurance companies to know whether the outcomes were produced by market capability or investment capability. In addition, efficiency differences among different characteristics of the firms will be investigated and comparisons made of the efficiency of domestic and foreign companies, old and new companies, and different sized companies. The paper uses the Tobit regression model to examine the factors that significantly influence managerial efficiency. Finally, based on the measurement of managerial efficiency, a management decision matrix is developed to serve as a basis for an assessment of the competitive strategy of the 24 companies in Taiwan. Problem Issues Taiwan, with a land area of 36,000 square kilometers, has a population of 20 million people. Government in early days restricted the expansion of insurance industry due to the conception of Taiwan only had minimal growth in the non-life insurance market. Back in those days, there were only four companies acting as the oligopoly in Taiwan's non-life insurance market and these companies are: Taiwan Fire, Chung Kuo, Tai Ping and China Mariners. …

This paper aims to compare the various physician-patient relationship modes of these entities with the same patient and two distinguished trustees (a doctor and hospital) at the same time. This paper also explores the influential power over loyalty in view of affective trust, cognitive trust and satisfaction, and expects to verify the mediator pattern of satisfaction between trust and loyalty. The study poses: Is there a discrepancy between two active modes of medical services—physicians- hospitals? In this study, a stratified sampling method was used to collect data. Participants were outpatients of a large teaching hospital in northern Taipei city. In addition, a structural equation model(SEM) is used for theory testing and development. The results show that whether the object is a physician or hospital, affective trust, cognitive trust and satisfaction had a si...

Facing the driving force of e-business, firms ought to adapt business strategy and take electronic integration strategy. This paper uses strategic management and transaction costs perspective to study the effects of uncertainty, technology system, business strategy and experience on e-business integration strategy. This research selects Taiwanese semiconductor and information firms to conduct case study. This paper finds that the information intensity, e-business experiences, integration intentions and strategy types have significant influence on electronic integration. And the effects of demand uncertainty, technology complexity and business scope on electronic

This paper uses the effectiveness model to measure the relative managerial performance and performance change of 50 listed corporations of the electronics industry under multiple financial ratio criteria. On the basis of the measurement of managerial performance, the entire industry can be partitioned into six clusters. Effective management strategies are developed specifically to each of six clusters of electronics industry. It was expected that this study would provide improvements to the existing financial ratio analysis; at the same time, illustrate the linkage between performance evaluation and strategy formulation for future business management needs of managers.

One major challenge in DfE implementation is how to effectively deal with the mix of the both the desirable outputs (to maintain or improve traditional product attributes) and the undesirable outputs (to reduce environmental impacts) in the design process. In this paper, we develop a new Data Envelopment Analysis (DEA) model for DfE performance evaluation where the simultaneous increase of desirable outputs and decrease of undesirable outputs are considered with a focus on identifying inefficiency as a result of higher levels of undesirable performance. We show that our proposed method is capable of establishing a benchmark with lower undesirable outputs for an inefficient decision making unit (DMU) than other models in the existing literature. We also use empirical data to demonstrate the applications of our DEA model in evaluating the sustainable design performances of different vehicle designs for the automobile industry. By treating the undesirable factors as the dominating factors in evaluating a DMU's sustainable design performance, our model can help identify the most eco-efficient way to improve the performance attributes of a product while minimizing its various negative impacts, such as greenhouse gas emissions, water pollution, and solid wastes, on the natural environment.

Adopting a simple and effective approach to stock selection to achieve higher returns is a key concern for investors. This study takes listed companies is Taiwanese electronic component industry as investigative subjects, and examine a study period running form 2001 to 2004, a period during which the Taiwan stock market experienced both bull and bear markets. This choice of study subject and study period helps achieve the objective of his study of providing a reference for individual and institutional investors in making stock-selection decisions by constructing a simpler, more stringent and effective stock selection model. This study assesses relative operating performance using the DEA additive model and relative stock price evaluation by the Grey situation decision model. The evaluation results are then used to further classify listed stocks based on four attributes. Empirical results indicate that the proposed stock selection model can predict stock returns, enabling both institutional and individual investors to reduce the risks associated with equity investments. Results of this study further demonstrate that DEA is combined with Grey situation decision extremely effective in devising stock selection strategy.

This paper is to discuss the management strategies formulation of the international tourist hotel industry in Taiwan based on the efficiency evaluation. First, data envelopment analysis (DEA), developed by Charnes et al. (Eur J Oper Res 2(6):429–444, 1978), is used to measure the relative managerial efficiency of the international tourist hotels in Taiwan. Through the Kruskal-Wallis, Taiwan’s international tourist hotels are divided into different strategic group. Secondly, by way of factor analyses of industry strategies, a clear picture of the industry strategies and features are identified. Consequently, the appropriate management strategies for different market segments are discussed. The research shows that the efficiency of international tourist hotels is different due to their managerial styles. International tourist hotels can be categorized into three groups: international cooperation; domestic franchise; and independent. “Target market”, “product differentiation”, “the degree of vertical integration”, “economics of scale”, “location” and “competitive edges” is concluded as the key factors to the formation of the managerial strategies. These six variables are used to discuss the managerial strategies of each market segment. The result of this paper will provide useful information for future business management needs of managers. Also, they may serve as valuable reference to the relevant authority of tourism.

Our two-stage approach provides the same superefficiency score as that obtained by the Super SBM model when the evaluated DMU is efficient and yields the same efficiency score as that obtained by the SBM model when the evaluated DMU is inefficient. The projection identified by the Super SBM model may not be strongly Pareto efficient; however, the projection identified from our approach is strongly Pareto efficient.
