Geographical patterns and their changes of fruit and vegetables supply system of Japan under the rapid increase of imported vegetables.

考察了日本国内的水果和蔬菜供应制度，并对供应日本的亚洲国家进行了比较。在日本，自20世纪90年代以来，新鲜蔬菜的进口显著增加，从蔬菜运输统计数据可以看出，大的生产者越来越大，而小的生产者越来越小。同时，从几个农产品批发市场的研究来看，大城市和小城市之间的批发价格差距加大了。亚洲国家增加了对日本的出口，特别是中国增加了出口量，韩国和东南亚国家增加了单位出口额。从中国和韩国国内供应系统的案例研究来看，它们都是对日本的主要出口国，而且都已经建立了全国性的新鲜蔬菜供应系统，与日本类似。对日出口额不仅反映了日本与这些国家之间的经济差距，也反映了出口国内部的区域和国内经济差距，这是一个重要因素。根据上述结果，考虑到中国幅员辽阔，人口众多，而韩国相对较小，日本应该重新审视其国内果蔬供应体系和国际贸易。事实上，大量进口水果和蔬菜对日本国内的供应体系产生了相当大的影响，因此日本应该寻求一种新的供应体系，从许多亚洲国家进口，而不是依靠大规模生产或由在市场上享有较高经济地位的消费者和买家驱动的消费体系。

The domestic fruit and vegetables supply systems of Japan and Asian countries that supply Japan were examined and then compared.In Japan, since the 1990s, imports of fresh vegetables have markedly increased, and larger producers have become larger while smaller producers have become smaller, as shown by vegetable shipping statistics. At the sane time, from studies on several agricultural wholesale markets, disparity in wholesale prices between large and small cities increased.Asian countries increased their exports to Japan, in particular, China increased its amount and South Korea and Southeast Asian countries their value per unit. From the case studies of the domestic supply systems of China and South Korea, both are major exporters to Japan, and both already have nationwide fresh vegetable supply systems, similarly to Japan. The amount of exports to Japan reflects not only the economic gaps between Japan and these countries, but also the regional and domestic economic gaps within the exporting countries, which is an important factor. In light of the above results and considering that China is vast with an enormous population while South Korea is relatively small, Japan should review its domestic fruit and vegetable supply system and the international trade. Indeed the large imports of fruit and vegetable have a considerable impact on Japan's domestic supply system, so Japan should seek a new supply system, importing from many Asian countries and never relyipg on mass-production or a consumption system driven by the consumers and buyers who enjoy a higher economic position in the market.
