Adjustment of Scientific Outlook on Development and China's Opening-up Strategy Scientific Outlook on Development is the new development of China's guiding ideology of socialist modernization by the new leadership. People-oriented, comprehensive, coordinated and sustainable development concept is not only the fundamental policy for China to build a well-off society in an all-round way and realize the coordinated development of domestic economy and society, but also the basic guiding ideology for China to handle foreign trade relations and lead the adjustment of opening-up strategy. Entering a new historical stage of all-round opening, China needs to reflect on the traditional opening strategy and mode under the guidance of Scientific Outlook on Development, solve the contradictions and problems in the development of open economy, explore new opening goals and ideas through the optimization and adjustment of opening strategy and opening system, and strive to improve the quality and efficiency of opening up while further expanding its opening up, so as to achieve comprehensive, coordinated and sustainable economic development. Keywords: Scientific Outlook on Development, strategic adjustment of opening to the outside world. The dilemma of China's traditional opening-up strategy from the perspective of Scientific Outlook on Development Since the reform and opening-up, China's opening-up has been deepening, and now it has formed an all-round, multi-level and wide-ranging opening-up pattern. However, while China's open economy has made remarkable achievements, there are also many outstanding problems. Especially after entering the new stage of all-round opening-up, China's traditional opening-up model and policy began to show unsustainable development dilemma. 1. The traditional policy of encouraging investment intensifies the contradiction of domestic development model. Expanding the scale of foreign capital utilization through preferential policies is a basic foreign capital policy that has been implemented for a long time in China since the reform and opening up. However, the long-term incentive investment policy has also brought serious side effects to China's economic and social development. First of all, China's long-term super-national treatment for foreign-invested enterprises has, to a certain extent, caused unequal competition between domestic and foreign-invested enterprises, inhibited the investment enthusiasm of domestic enterprises, and is not conducive to the long-term sustainable development of the national economy. Secondly, under the guidance of the traditional development strategy, governments at all levels regard the scale of foreign investment absorption as an important performance indicator, and they are also rushing headlong into the preferential policies for foreign investment, which has repeatedly exceeded the boundaries stipulated by national policies and harmed the overall interests of the country. Thirdly, under the cover of foreign capital incentive policy, there are ecological damage, resource waste and environmental pollution problems in China's utilization of foreign capital to varying degrees. Some local governments, under the guidance of a wrong view of political achievements, blindly introduced foreign capital and moved factories that were eliminated from abroad and polluted the environment to China for production, regardless of the actual situation of local resources and industrial structure, which caused devastating damage to the local ecological environment. 2. Extensive foreign trade growth mode leads to frequent international economic frictions. Associated with preferential foreign investment policy is extensive foreign trade growth mode. After more than 20 years of reform and opening-up, China has rapidly emerged as a world-renowned international trade power. However, due to the extensive foreign trade growth mode for a long time, China's foreign trade volume is huge, but its contribution to the growth of national wealth is relatively limited. First of all, from the perspective of trade structure, although China's total foreign trade has increased substantially in recent years, the trade structure and profitability are unreasonable, and the benefits that citizens get from foreign trade are very limited. Secondly, in recent years, the proportion of China's export products is increasing year by year, but the proportion of high-tech products is still very low. Third, China's traditional trade strategy is based on "earning foreign exchange through export". In order to encourage exports, the China government has adopted a series of preferential policies to promote exports, and maintained a "surplus" state of exports exceeding imports for a long time. With the continuous expansion of trade scale, the growth mode of China's foreign trade with a strong "mercantilism" color has been unsustainable. Fourth, the export of bulk commodities is likely to cause unnecessary international trade frictions, which is not conducive to the long-term sustainable development of China's foreign trade. Because of the cheap labor price, China's exporters blindly depress the price in the international market, resulting in the long-term situation that China's export products are increasing without increasing the price. At the same time, a large number of goods from China flood the international market, which is prone to dumping and unnecessary international trade disputes. 3. "Made in China" stays at the low end of the international value chain, endangering China's resources and energy security. Since 1990s, China's manufacturing industry has become the fastest growing country in the world. It should be said that the rise of China's manufacturing industry is the historical opportunity for China to seize economic globalization and international industrial transfer, the result of its own efforts, and the objective fact that China's comprehensive national strength is constantly improving. Although China's manufacturing industry is huge and growing rapidly, there are still many problems from the perspective of implementing Scientific Outlook on Development. First of all, the technical level, labor productivity and industrial added value rate of China's manufacturing industry are relatively low at present. Due to the lack of independent brands and core technologies, China's manufacturing industry is, to a great extent, only a "workshop" for large international multinational companies to produce and manufacture products in China, staying at the low end of the international value chain division. Secondly, an important factor for the rapid development of China's manufacturing industry is that China has a large number of cheap labor, which is a "double-edged sword" for the development of China's manufacturing industry. On the one hand, China's manufacturing industry has quickly gained a certain market position in the world by virtue of its international comparative advantage formed by low labor costs; On the other hand, the low labor cost causes the international low price of China's manufacturing industry, which makes China's benefit from the development of manufacturing industry very limited. Third, the rapid development of China's manufacturing industry has also brought severe challenges to China's energy and resource security. 4. Excessive dependence on foreign countries increases the risk of national macroeconomic operation. The overall acceleration of the strategy of opening to the outside world will certainly further strengthen China's economic ties with the world. It can be said that the increase in dependence on foreign countries is the result of China's opening to the outside world and the embodiment of China's opening to the outside world. However, if the external dependence is too high, it is impossible to control the external dependence factors independently. Once the external economic environment changes, China's economic development will face enormous potential risks. Therefore, in this sense, excessive external dependence is not in line with Scientific Outlook on Development. At present, China's dependence on foreign countries is getting higher and higher, mainly in the following aspects. First of all, China's economic growth is excessively dependent on foreign capital, which endangers the national economic security to a certain extent. From a technical point of view, foreign-funded enterprises represented by multinational companies firmly control the industrial technology in China market, and prevent the independent technological innovation and progress of China enterprises through patent strategy and technical standard strategy. Secondly, China's dependence on foreign trade is increasing year by year, which also brings potential risks to the sustainable development of China's export-oriented economy. In 2004, China's foreign trade import and export increased substantially, and China's dependence on foreign trade reached 70%. Third, China's important resources and energy are highly dependent on foreign countries, which easily leads to energy resources security problems. With the rapid economic expansion in China, extensive growth leads to high consumption of energy and raw materials, and China's dependence on the import of energy and important resources is becoming more and more serious. How to effectively reduce the external dependence of China's strategic resources and energy according to the requirements of Scientific Outlook on Development is one of the important strategic issues that China needs to pay attention to.
