There is a direct relation between the extension of product service life and the environmental protection and economic effect. Hence, it is imperative to develop a product service life effect model to assess the impacts of changes in product service life and the related energy consumption patterns on the environment and the domestic economy. In reality, the economy takes on form and is only capable of satisfying the demands of limited number. As stated in the previous article, in addition to recycling and waste reduction, we also dedicated efforts on the extension of the service life of our products to reduce the frequency of product replacement. Although GA products have a low replacement rate and direct impacts on the economy are minimal, we continue to upgrade product quality since we believe product quality is essential to the maintenance an excellent reputation.
