回答：Primary Data CollectionProblems of Primary Data CollectionAn alternative to secondary data is primary data collection. Primary data presumably provide more relevant information because they are collected specifically for the purpose in mind. However, the collection of primary data is an expensive proposition in terms of both money and time. Thus, the underlying purpose must justify the effort. For example, when a company has to make a decision about appointing a dealer for the occasional sale of its product in a developing country, it is not necessary to have primary data on the longterm market potential. On the other hand, if the company is considering the establishment of a manufacturing plant in the country, it may be important to undertake a market-potential study.Primary data collection in a foreign environment poses a variety of problems not encountered in the United States. These problems are related to social and cultural factors and the level of economic development. They can be grouped under three headings: (1)sampling problems,(2)questionnaire problems,and (3) the problem of nonresponse.原始资料收集原始资料收集的问题除辅助资料之外的另一个选择是原始资料的收集。原始资料或许能提供更相关的信息，因为它们是被有目的地特别收集来的。不过，原始资料的收集就金钱和时间而言是相当昂贵的。因此，根本的目的必须证明努力是正确的，例如，当一家公司必须为一个在发展中国家零售它的产品的经销商做的决定时， 没必要在长期的市场潜力上获得原始资料。另一方面， 如果公司考虑在这个国家建立一个制造工厂，那么承担一项市场潜力研究可能是重要的。在国外，原始数据的采集遇到了许许多多在美国不曾遇到的问题。这些问题是与社会、因素和经济发展的水平有关的。 他们可以归为3类：(1)取样问题，(2)调查表问题，(3)无反应问题。
