to jump over the barriers. Therefore, the market becomes saturated, with only price competition. This is the fate of global competition, only the fittest companies survive. Pressure of product life period High-tech products rapidly produce a smaller percentage of revenue unless they are improved and developed continually. This puts a premium on innovation for companies which wish to remain profitable. Lack of upgrading can therefore lead to a loss-making position. Pressure of value-added The value-added of an enterprise can be said to represent the potential for profit. Mature technology, low cost requirement for entry, and universalization of technology make it easy found a so-called "low-profit" enterprise, also known as low-value-added industries. Normal manufacturing and assembly enterprises are low-value-added industries, and in order to survive, can only keep expanding production capacity to maintain profits. But as long as the market is shrinking and/or product prices are decreasing, sales income will no longer be growing.. Trend of industries development In order to overcome the pressure of low added value, enterprise's only recourse is to move towards high-value added industry trends. Mastering the key technology and key components is high added value; general manufacturing or OEM is low added value; product integration service also produce high added value. Conclusion Aiming for high value-added products is only way to have a high potential for profit, therefore to ensure business continuity. Applications Inspiration Smile curve theory seeks to show that the success of products is inextricably related to concept, research, brand spreading and marketing. Those factors require the company to hire and retain highly skilled, intelligent, professionals. Typically, those professionals will be highly paid, so that countries with high smile curve slope companies will generate a higher GDP, therefore generating growing gaps between countries. Comparing developing and development countries The United States and other developed countries have maintained highly slope of the smile curve; however developing countries such as India and China have previously been confined to low-level employing and manufacturing. Therefore, if developing countries want to achieve the high slopes of the smile curve, they need more professional analysts, researchers and brand developers to reach higher levels of economic growth. In other words, if developing countries want to compete with developed countries equally, they must use a highly skilled and knowledge workforce, government needs to invest heavily and support higher education.
