JAPAN-NETHERLANDS TRADE SITUATION IN THE 18th CENTURY

这项研究旨在揭示18世纪日本与荷兰的关系。首先，我试图弄清17世纪的商业状况，以确定下个世纪衰落的原因。在研究了这些情况后，我指出了18世纪商业衰落的问题。荷兰东印度公司在17世纪20年代针对一个严重的情况对日荷贸易进行了调查，我参照该公司的报告推动了该公司如何执行商业政策，并明确了长崎商业制度的重组。我想，在1750-60年代，长崎的两位知事对长崎贸易体制的改革持积极态度。在本研究中，我特别关注了17世纪60年代的石屋宾果。我指出了他改组的内容，即金银进口问题、从长崎市到德川县的税收问题、口岸税制度等。此外，我还发表了荷兰东印度公司关于日本樟树贸易的论文，并将用英文发表关于日本铜贸易的文章。最后，我对江户时代的日荷贸易与西堡的一篇文章进行了例证。虽然我承认他在自然历史领域的成就，但他可能会指出一些问题和错误。

This study aims to shed light on the relations between Japan and the Netherlands in the 18th century. First I tried to clear up the commercial situation in the 17th century, for determining the cause of the decline in the next century.After reseraching in the conditions, I pointed out the problems that the trade was on the decline in the 18th century. The Dutch East India company made an inverstigation of Japan-Netherlands trade in 1720s in relation to a serious situation.I shoved how the company carried out a commercial policy with refering the report by the company.I also made clear that the reorganization of the commercial system in Nagasaki. I'm supposed that two governors in Nagasaki took positive attitude to the reform of Nagasaki trade system in 1750-60s. I particulary focused on Ishigaya Bingo no kami in 1760s in this study. I pointed out the contents of his reorgnization, that is the problems of gold, silver imports, taxes from Nagasaki city to Tokugava gouvernuent, a system of Kokusen(port dues), etc.Moreover I publishied a paper about Japanesc camghor trade by the Dutch East India Company, and will also publish about Japanese copper tradc with English. Lastly I ciriticized an article of the Japan-Netherlands trade in Edo era with F.von Siebold.l could show some problems and mistakes, though I admit his achievement in the field of natural history.
