改革开放以来，中国经济取得了巨大的成就，中国业已成为吸引外商投资最多的发展中国家。在中国经济对外开放进程中，国际直接投资的大量流入对中国的经济发展起着至关重要的作用。随着中国经济的迅猛发展，外商直接投资对中国经济产生着越来越深刻而重要的影响，但怎样更合理利用国际直接投资来进一步保持中国经济持续稳健发展，仍然是一个很严峻的问题。其原因主要存在于：首先，外商直接投资在区域上的不均匀性。外商直接投资主要集中在东南沿海地区，虽然极大地促进了沿海地区经济的高速发展，但是这种现象也加剧了中国地区经济发展的不平衡，使中国中西部地区与东部的贫富差距越来越大。其次，由于制约于不了解外商直接投资区位选择的影响因素，各地区在吸引外商投资时盲目在优惠政策上攀比，不仅造成了企业之间的不公平竞争环境，更是导致了国家利益的大量流失。再者，对于不同来源国家和地区来说，在华投资所受到的影响因素也必然各有区别，怎样充分利用中国自身优势来最有效地吸引更多来自全球各个地方的外商投资也显得尤为重要。本文针对我国外商直接投资的主要来源体美国、英国、德国、日本、韩国、新加坡、香港、台湾，利用我国2001-2009年的省级面板数据，对以上不同来源体外商直接投资在我国的区位选择因素进行了比较分析，得出结论：集聚因素是影响各个来源体外商直接投资在我国区位选择的最重要的因素，对所有来源体外商直接投资都有重要影响。相比集聚因素，传统的区位选择因素如当地的市场规模、劳动力资源、基础设施、制度因素均成为“低阶优势”，对外商直接投资的影响不稳定，随来源体的不同而有所区别。当地的市场规模仅对新加坡的外商直接投资有显著的正向影响；与欧美日韩国家相比，香港、台湾、新加坡的外商直接投资对劳动力因素更为敏感，尤其是台湾，其外商直接投资与劳动力成本显著负相关，且系数远远大于其它几个国家；对于大多数来源国家和地区而言，基础设施因素已不是影响外商直接投资的最主要因素；制度因素对外商直接投资的影响逐渐减弱，仅对新加坡、香港等少部分来源国家和地区的外商直接投资有影响。

Since China's reform and opening up, our country has been favored by FDI. With rapid economic development, foreign direct investment is playing a more and more important rule on China's economy. But how we can use FDI to sustain the continued growth of the Chinese economy is still a very serious problem. Due to historical, economic policy and other reasons, the regional distribution of FDI in China is seriously imbalance. Because of not understanding the location factors of FDI and not recognizing there are differences between different origins’ location factors, governments of all Provinces always take similar measures to attract foreign investment.In this paper, I used the latest data of China’s FDI from various origins, such as United States, Britain, Germany and so on to study the location factors of foreign direct investment, then make an comparative analysis between these origins. Test results showed that: the location factors of China’s FDI by different origins are very different. Agglomeration factor is the most important factor of foreign direct investment’s location choice in China. It has a significant impact on all sources of foreign direct investment. However, compared to the agglomeration factor, the traditional locational factors such as local market size, labor resources, infrastructure, and institutional factors are a "low-level advantage". Their impacts on foreign direct investment are unstable. The impacts vary as different origins. The local market has significant positive effects only on Singapore’s foreign direct investment. Compared to Europe and the United States, foreign direct investments from Japan, South Korea, Hong Kong, Taiwan, and Singapore are more sensitive on labor costs. However, the impacts of infrastructure factors and institution factors on FDI are gradually weakening.
