Equipment replacement policy: a survey

Over the past ten years there has been a considerable increase in application of theoretically correct measurement methods in determining the economic life of equipment. Approximately 89% of the firms surveyed have equipment replacement policies. The discounted rate of return method is the most widely used in determining the service life of equipment; the MAPI formula is not widely used. Difficulties in applying a replacement policy can be classified into three groups: operational, organizational, and economic. The problems mentioned most often are operational. In organizational difficulties there is usually a lack of coordination between staff and line managers. Economic problems are generally the limited funds available for equipment replacement. Formal educational programs are lacking for the development of equipment replacement managers. For the firms having replacement policies, individuals with engineering degrees are preferred over those in other disciplines for the management of the equipment replacement policy.

论中国企业“走出去”的“软肋”——品牌弱势

跨国公司间的竞争最终是品牌的竞争,而品牌弱势却日益成为中国企业走出国门的“软肋”。中国企业品牌弱势主要表现在跨国名牌严重匮乏、产业层次较低;过分满足“贴牌生产”和“中国制造”,从属地位严重;国外品牌势力强大,自主品牌“举步维艰”;品牌保护意识薄弱,知名品牌被抢注现象增多等。针对品牌弱势,我们应完善自主品牌发展的激励机制;改善投资环境,为培育品牌创造条件;发挥行业协会作用;加大研发力度,提高自主创新能力;提高品牌意识,加强商标管理;重视产品质量,借鉴国际经验,学会推广和维护品牌。
