BYD自動車のファジィVRIO分析

　It is generally understood that the Chinese market is now an integral part of the world market and international automobile companies are making efforts to gain access to it. To expand their market share in China, companies implement various strategies, making competition fiercer. As Chinese automobile companies are not well-known world-wide, BYD is suitable for analysis as a representative Chinese automobile company. Firstly, the history and outline of the company are summarized, then the strengths and weaknesses of the corporate environment are described using the fuzzy VRIO (Value, Rarity, Inimitability and Organization) analysis method. Applying fuzzy theory in the analysis of the management environment, for instance, VRIO analysis can enable the formulation of more effective strategies. This application of fuzzy theory to management methods is intended to contribute to the future development of the Chinese automobile industry. This paper clarifies the significance of the competitive advantages of BYD Auto using fuzzy VRIO analysis

中国自主自動車業界のファジィ5Ｆ分析

　The Chinese market is indispensable to international automobile companies, who are thus expanding investment in the country’s automotive industry. To increase their market share in China, automobile manufacturers and independent automotive enterprises have implemented a series of management strategies. Consequently, competition in China is becoming increasingly intense. At the same time, Chinese automobile companies have no international brand recognition.　 In this paper, an independent automobile enterprise of China examined using the fuzzy 5F （threat of new entrants , rivalry among existing firms , threat of substitute products or services , bargaining power of buyers , bargaining power of suppliers） analysis. We think that the application of fuzzy theory to management methods will contribute to the development of the Chinese automobile industry

奇瑞自動車の競争戦略分析

　The Chinese market is indispensable for the world’s automobile enterprises, and they have all strengthened their investment in that market. Therefore, in order to expand their market shares in China, all automobile companies and independent automotive enterprises have implemented a series of management strategies, and, as a result, made the competition in China more intense. However, Chinese automobile enterprises are not known to the outside world.　Therefore, this paper selected the independent automobile company Chery as an example, based on an analysis of the history of the company, using SWOT and five competive forces (5F) methods. Finally, I would like to put forward four solutions to solve the current problems. Through this paper, We wish we could make contribution to the development of Chinese automobile enterprises in the future

Sm–Nd Isochron Age Constraints of Au and Sb Mineralization in Southwestern Guizhou Province, China

Southwestern Guizhou, China, is famous for hosting clusters of Carlin-type Au, Sb, and Hg-Tl deposits. These deposits are thought to be the products of a low-temperature hydrothermal metallogenic event. Calcite and fluorite are common and widespread gangue minerals in Au and Sb deposits, respectively. Ore-related calcite commonly coexists with stibnite, realgar, and orpiment at the periphery of high-grade orebodies in Au deposits, while ore-related fluorite is generally intergrown with stibnite in Sb deposits. In this study, ore-related calcite and fluorite samples from representative Au (Zimudang) and Sb (Dachang) deposits, respectively, were separated, and the rare earth element (REE) concentrations, Sm/Nd isotope ratios, and Sm–Nd isochron ages were analyzed. This study aims to determine the formation ages of the calcite and fluorite and to constrain the age of low-temperature metallogenic event in Southwestern Guizhou. The calcite and fluorite samples contain relatively high total concentrations of REEs (8.21–22.5 μg/g for calcite, 21.7–36.6 μg/g for fluorite), exhibit variable Sm/Nd ratios (0.51–1.01 for calcite, 0.35–0.49 for fluorite), and yield Sm–Nd isochron ages of 148.4 ± 4.8 and 141 ± 20 Ma, respectively. These ages are consistent with the age range constrained by the low-temperature thermochronology of zircon (132–160 Ma), crosscutting relationships of stratigraphy or intrusions (96–160 Ma), and previous dating results (135–150 Ma) in Southwestern Guizhou. Collectively, the ages obtained in this study add new evidence to previous geochronology studies, such that the low-temperature hydrothermal mineralization in Southwestern Guizhou can be constrained to 135–150 Ma, corresponding to the Yanshanian orogeny, which was associated with a weak extensional tectonic environment
