Theoretical analyses on the firms' global location and/or organization choice behavior and the trade and industrial policies of the government

在本文的研究中，我们成功地获得了许多以往文献没有发现的关于企业出口或对外直接投资在不同情况下的最优区位选择问题的新的、有意义的结果。此外，我们还分析了来源国和东道国政府的最优贸易和/或产业政策对企业战略行为（包括区位选择行为）的影响。在跨境污染等国际环境问题和不完全竞争条件下援助国与接受国的互利经济援助等问题上也取得了新的研究成果。

In our research, we have succeeded in obtaining many new and significant results, which preceding literature did not find, on the firms optimal location choice problem whether the firms export or undertake foreign direct foreign investment in various circumstances. Also we have analyzed the optimal trade and/or industrial polices of the governments of the source and host countries on the firms strategic behavior including location choice behavior. We also obtained novel results on the international environment problems including cross border pollutions, and on the mutually beneficial economic aid for both donor and host countries under imperfect competition.
