    问答题
    Discuss, and decide together:　　● What measures are most effective for identifying new export markets?　　● How to maintain sales in export markets?

    正确答案：
    【参考范例】
    Candidate A=A Candidate B=B
    A: Well, first of all, we should generalize the main points in the article. The first point is to highlight the importance of adaptation. When the company started its globalization, it had to decide which product lines to begin with. The company had a framework to identify product lines that were suitable for early globalization. Each line of business in the company’s portfolio had to be evaluated along two dimensions, that is potential pay-off (expected returns) and potential risk (degree of local adaptation required).
    B: I see what you mean. Well, it’s true that we had made a lot of efforts on adaptation of our products. Each line of business in the company’s portfolio had been evaluated along two dimensions with the first dimension focused on the potential profits of globalization and the second dimension on the level of adaptation that was required to enter foreign markets.
    A: Although you’re comments are well meant, they are a little vague. Enough detailed information should be given about it. Because any new development involves risk, great degree of local adaptation means great risk of failure. While the good brands could offer globally standardized services successfully, the retirement communities and the long-term-stay companies would demand far more local adaptation. Thus, full-service companies provide both a greater pay-off and less risk, so they are the best candidate for globalization. We should inform the readers of the way to maintain sales in export markets.
    B: Yes, you’re right. As to how to maintain sales in export markets, firstly, we need to put the famous brands into the framework. After that we should try to keep a worldwide presence. A worldwide presence will add value to a company. Maintaining a company presence refers to maintaining its sales in export markets. To adapt a product for a foreign market could involve risks. Therefore, we need to conduct a study about feasibility first.
    A: Absolutely. Besides, companies should try to get advice from consultants on choosing the right products to export. The consultants shall also give advice on choosing the most suitable foreign market and on the best way to enter a market. Then, what about the specific steps to enter a foreign market? What do you think are the safest method for it?
    B: Well, as you may know, the safest method for a company to enter a foreign market is to have an agreement with a local company. And another safe method is to set up its own local production. It is also comparatively safe to find a joint venture partner.
