A person from the Department of Economic and Trade Relations of the Ministry of Commerce told reporters yesterday that the creation of market demand is mainly focused on two aspects. First, maintain the demand of China's traditional markets for China and achieve growth. Second, take further steps to expand emerging markets. In recent years, China's exports to some emerging markets have grown rapidly, and the expansion of new markets has created greater market opportunities for diversification of export markets. Therefore, in the future, China will increase its implementation in this area, thereby reducing its dependence on major developed markets.
Li Jianfeng of Shanghai Securities said that the creative needs of the Ministry of Commerce have started from the Marshall Plan of the United States after World War II, creating demand for Chinese exports in foreign markets through international lending and international project assistance, thus driving domestic exports. .
According to the latest data from the Ministry of Commerce, the total import and export volume of the country from January to July was 1,146.71 billion US dollars, down 22.7% year-on-year. Among them, exports were 627.1 billion US dollars, down 22%; imports were 519.62 billion US dollars, down 23.6%; the surplus was 107.48 billion US dollars, down 13.1%. In July, the national total import and export value was US$200.21 billion, down 19.4% year-on-year and 9.6% quarter-on-quarter. Among them, exports were 105.42 billion US dollars, down 23% year-on-year and 10.4% quarter-on-quarter; imports were 94.79 billion US dollars, down 14.9% year-on-year and 8.7% quarter-on-quarter.
The above-mentioned person from the Ministry of Commerce said that from the perspective of foreign trade data, since the world is falling, China is undoubtedly also falling, which is certain. However, at present, some situations reflect that China’s share in the main market has not declined. Therefore, after the foreign economic situation improves, my foreign needs will be restored in time.
Guo Tianyong, director of the China Banking Research Center of the Central University of Finance and Economics, said that it is first necessary to affirm the effective role of expanding domestic demand. As the government's 4 trillion investment in the first half of this year will play an indelible role in achieving China's GDP. Of course, the role of expanding domestic demand is non-sustainable. Therefore, the development of exports itself cannot be ignored. An effective way to expand exports is to strengthen and increase the pertinence and flexibility of export commodities and create advanced products that can guide market demand.
Guo Tianyong said that in order to achieve the above objectives, it is necessary to guide the policy and adjust and guide the industrial policies of export enterprises, including a series of policies such as tax rebates and subsidies that have been issued before, and so on. At the same time, certain measures have been introduced to encourage enterprises to carry out technological upgrading and product innovation to promote the transformation of enterprises.
"From the perspective of the company itself, it is necessary to actively increase the investment in scientific research and provide one-stop service for production, supply and marketing in the international market, in order to comprehensively build the brand of the enterprise." Guo Tianyong said.
Li Jianfeng also said that in order to promote exports, product innovation can be vigorously promoted, but this does not mean abandoning labor-intensive export products. At the same time, there are technical measures such as using international rules to avoid trade protection. Of course, we cannot ignore the role of expanding domestic demand to prevent the return to the investment-export development model as the economic recovery of developed economies drives exports.
