对近年来日本线材及其制品的生产和进出口情况进行统计分析 ,结果显示 ,日本线材年产量基本不变 ,普通钢线材和特殊钢线材产量变化呈互补性 ;金属制品年产量 1998年急挫后有所回升 ,不同品种有不同的变化规律 ,低碳钢丝、PC钢丝、钢丝绳等产量下降 ,钢帘线和高碳镀锌钢丝等产量增加 ;制品产量与线材产量之比略有下降 ,但仍处于较高水平 ;线材进口呈下降趋势 ,出口呈增加趋势 ;金属制品进口呈增加趋势 ,出口量波动较大 ,总出口量远大于进口量。日本对中国的线材出口远大于进口 ,但出口呈下降趋势 ;对中国的金属制品进口远大于出口 ,呈增加趋势 ,并对产生这一结果的原因进行分析 The statistical analysis on the production and import and export of Japanese wire rods and their products in recent years shows that the annual output of Japanese wire rods remains basically unchanged, and the output changes of ordinary steel wire rods and special steel wire rods are complementary; the annual output of metal products has plummeted in 1998. After the recovery, different varieties have different patterns of change. Production of low-carbon steel wire, PC steel wire, steel wire rope, etc. decreased, production of steel cords and high-carbon galvanized steel wire increased, and the ratio of product output to wire production decreased slightly. It is still at a relatively high level; import of wire rods is declining, and exports are increasing; imports of metal products are on the rise, exports are volatile, and total exports are much larger than imports. Japan’s wire rod exports to China are much larger than imports, but exports are declining. Imports of metal products to China are much larger than exports, showing an increasing trend, and the reasons for this result are analyzed.
