| Recalling the history of the world economy, it is not difficult to find the emergence and development of circular economy, is the reflection of the whole society of human when facing resource shortages, environmental pollution and other common problems , and the reflection of the traditional economic growth .Since the Industrial Revolution, While human society created huge material wealth, it also paid a great cost of resource and environment .The theory of spacecraft of circular economy which can be seen as the seeds. The two world energy crisis in the 1970s sparked a profound reflection of economic growth ; In the 1980s people began to explore the road of sustainable development; In the 1990s, the United Nations Conference on Environment and Development take a formal sustainable development road .In the crisis of global environment degradation and resource pressure, circular economy , as the most advanced development model in the modern economic world, emerged. Take the road of technological innovation especially in developed countries has become a comprehensive national competition and race for high ground of a new international development competition. Japan as one of the countries explored the circular economy in the early stage, first put forward the slogan of building a recycling-oriented society. Technological innovation and application system of circular economy ,as an important part of circular economy which is also a necessary and important means , has achieved many achievements, walking in the forefront of the world.This article is divided into four parts:The first part has defined the concept of the circular economy and technological innovation, compared the difference between technological innovation of circular economy and traditional technical innovation .Then illustrate the implications of technological innovation in circular economy, which form the theoretical basis for this article. Circular economy is a fundamental change of traditional economic growth, efficient use of resources and recycling as its core and reduce, reuse, recycle as principle. Technological innovation of circular economic is application in practice based on the concept of circular economy.The second part is the key part of this article. First of all, illustrated the motives of the different industries to apply technological innovation , and then focus on technology innovation in the industry .Including technological innovation in agriculture, industry, services and venous industry. The promotion and application of circular economy in Japan in agriculture, mainly reflected in Japan's environmental conservation type agriculture, technological innovation covering land and water conservation, soil improvement, the use of biomass and so on ; in the industrial technology, select the manufacturing technology, green building technology and new energy technologies described, technological innovation, from product design, resource exploitation, manufacturing, waste and new energy applications in various stages; Circular economy applications in the service industry mainly in commodity circulation sector and the financial sector, technology innovation and management innovation co-exist; is worth mentioning the Japanese Venous Industry technological innovation, as the industry make waste into renewable resource and venous industrial technological innovation reduce waste and expanding employment opportunities at the same time.The third section describes the support system of technological innovation in Japan. The main parts included the Government, enterprises and related organizations, the institutional support system included the legal system and policy system. This article analyzed the responsibilities of government, enterprises, organizations in respective. The last part of this article briefly described the achievements of technological innovation and future development in the circular economy. Achievements which included the achievements of the industry's technological innovation, the effectiveness of resource and energy conservation in the whole society, and new energy effectiveness and environmental effectiveness. The achievements depended on the Japanese industry's three-dimensional industrial system, circulation system within the enterprise, all industries and arterial networks between industry and the combination of venous industry. Then illustrated a circular economy in Japan in recent years technological breakthroughs achieved and development trends of the next decade. |
