C国太乐厨具有限公司（简称太乐公司）创办于1996年。近20年来，太乐公司运用成本领先战略，迅速提高市场占有率，在国内外享有较高的知名度。太乐公司集中全部资源，重点发展厨具小家电产品。公司利用与发达国家企业0EM合作方式获得的设备，进行大批量生产，从而获得规模经济优势。在此基础上，公司多次主动大幅度降低产品价格，使得生产该种产品的企业都无利可图，在市场上既淘汰了高成本和劣质企业，又令新进入者望而却步。 太乐公司实行24小时轮班制，设备的利用率很高。因而其劳动生产率同国外同类企业基本持平。同时，由于国内劳动力成本低，公司产品成本中的人工成本大大低于国外家电业的平均年水平。 对于一些成本高且太乐公司自身有生产能力的上游资源，如集成电路等。公司通过多种形式自行配置生产，这样，一方面可以大幅度降低成本，确保质量，降低经营风险。另一方面还可以获得核心元器件的生产和研发技术。而对于一些成本高、自身还不具备生产能力的上游资源，公司由于在其他各环节上成本低于竞争对手，也能够消化这些高成本投入的价格。近几年来，C国厨具小家电的销售数量每年递增30％左右，吸引了众多国内外大型家电企业加人。这些企业放弃了原有在大家电市场走的高端产品路线。以中低端的价格进入市场。这些企业认为，在厨具小家电市场，企业销售的都是标准化的产品，消费者大都对价格比较敏感，价格竞争仍然是市场竞争的主要手段。要求：

从市场情况和企业资源能力两个方面，简要分析太乐公司在C国厨具小家电市场实施成本领先战略的条件。

With U.S. companies sitting on an estimated $1.8 trillion in cash, it raises the question: Why aren’t they deploying more of their hoard to expand their businesses Or one might channel John Maynard Keynes to ask: Where have the "animal spirits" gone Although capital spending in the U.S. is up 12 percent since the lows of early 2009, it’s still running $88 billion below the peak of $1.34 trillion reached in the first quarter of 2008, says Joseph LaVorgna, chief U.S. economist at Deutsche Bank. He doesn’t expect capital spending to catch up to that peak level and officially start to expand until the second quarter of 2011. (LaVorgna’s definition of capital spending includes physical equipment and software, but not structures such as new stores or manufacturing plants. Spending on structures is about 2 percent of gross domestic product, one-third the size of capital sending’s contribution to GDP, he says.)

"The trend and momentum have definitely turned and it’s just a matter of time before you see other companies give way to capital spending, and eventually that will result in hiring," says LaVorgna. But with spending running $88 billion below peak, he says employment "should be farther along than it is." Companies that have built up a lot of cash are starting to take some chances such as expanding into new markets, which requires hiring new workers, says John Challenger, chief executive officer of Challenger, Gray & Christmas, an employment consulting firm. U.S. companies have announced the hiring of 118,209 new employees through August, according to data collected by the firm.

So who’s stepping up to the plate Some companies refuse to be cowed and are taking big, if calculated, chances, including ambitious capital projects, hiring new workers, and expanded investment in research and development, according to growth-oriented mutual fund managers contacted by Businessweek.com. If there’s a common denominator, it’s a perceived opportunity and confidence in sustainable demand, whether due to new trends in technology or to new markets that need certain products. Other names came from a list of the top-hiring U.S. companies through July 2010 compiled by Challenger, Gray & Christmas.

"We don’t spend capital unless we have a new contract to supply oxygen, nitrogen, or hydrogen to our customers," says James Sawyer, Praxair’s chief financial officer. "Those are 15-year contracts with minimal take-or-pay clauses written into them, which ensure we will get a good return on our capital investment, regardless of how the rest of the economy is doing."

Some younger outfits with entrepreneurial managers who have lived through a few business cycles think their companies may be able to steal a march on competitors more reluctant to spend, says Aram Green, manager of Clear Bridge Advisors Small Cap Growth Fund. "There’s clearly been a decision by management that ’This is not the time to take our foot off the accelerator. In fact, it’s time to push harder and further distance our product from the competition.’\
