According to the report, ZTE is the most competitive telecom vendor in China, India, emerging Asia-Pacific market, Africa and Eastern Europe. ZTE tallied the highest score in four out of seven categories the Yankee Group used to measure the CDMA competitiveness of each vendor. The seven key evaluation factors were price, technology, existing installed base, product portfolio, integration capability, government support and company culture.展开更多

During the period of less than four years, it has completed two big electrolyticaluminum smelters and started the construction of a project of oxide of alumina. With its rapid speed, advanced technology and equipment, and high efficiency, the company has created a miracle in aluminum industry. From the viewpoint of strategic management, the author analyzes the strategic thinking of its entry into the aluminum industry; the strategic measures to build the company into the most competitive enterprise in this industry, and how to maintain a sustainable competitive advantage. Meanwhile, the paper plays an important reference role for the analysis of the private economy, and the enterprises with diversified thinking and those wishing to expand aggressively.展开更多
