由于国土狭窄和资源贫乏,日本一直把开发海洋资源置于优先地位,大力鼓励渔业、造船业和近海石油、天然气工业的发展。近年来,日本又在积极发展三种利用海洋资源的技术,即海洋热能转换、海水提取铀及深海采矿。日本政府和工业界认为,对国际工业原料的过分依赖会造成日本工业的脆弱。因此,他们很注重海洋资源的利用,把它作为长远的战略性任务。
Due to its narrow territories and poor resources, Japan has always prioritized the development of marine resources and strongly encouraged the development of fisheries, shipbuilding and offshore oil and gas industries. In recent years, Japan has also actively developed three technologies that make use of marine resources: conversion of marine thermal energy, extraction of uranium by seawater and deep-sea mining. The Japanese government and industry believe that over-reliance on international industrial raw materials can cause the Japanese industry to be vulnerable. Therefore, they pay great attention to the utilization of marine resources as their long-term strategic task.
