我国举办中外合营企业的重要目标之一,就是要通过合营企业引进一些用许可证贸易方式不能引进的技术。在实践中,通过许可证贸易方式一般都不能得到最先进的技术。许可方用以交易的技术一般是已经在某些国家专利机关登记,并已有大量产品上市的。这种因登记而取得的专利权的专利技术,在转让时已失去了它特有的商业价值,有些很快会失去其先进性,有些甚至已为最新技术所代替。而跨国公司往往把最新发明作为技术秘密,既不公开申请专利,也不在国际市场上出售,而是将其用于独占性的商品生产,垄断市场,获取垄断利润。目前,从 One of the important goals for China to hold Sino-foreign joint ventures is to introduce some technologies that can not be imported by means of a license trade through joint ventures. In practice, state-of-the-art technology is generally not available through the licensing trade. The technique used by the licensor to trade is generally already registered with the patent offices of some countries and a large number of products have been placed on the market. The patented technology of such patents obtained through registration has lost its peculiar commercial value at the time of transfer, some of them will soon lose their advanced nature and some of them have even been replaced by the latest technology. However, multinational corporations often regard the latest invention as a technical secret. They neither patent the patent publicly nor sell it in the international market. Instead, they use it for exclusive commodity production, monopolize the market and obtain monopoly profits. At present, from
