From 79 to 35, 43 to 11, and 44 to 32, the reduction in a set of numbers has attracted a lot of attention in the field of foreign investment. 
This set of figures comes from the recently revised “Guidance Catalogue for Foreign Investment Industries” (hereinafter referred to as the “Catalogue”) published by the National Development and Reform Commission. The Catalogue has been officially open to the public for comments from November 4, which relaxed the general manufacturing. Foreign investment in industry and service industry, and stipulated that the number of restricted foreign investment projects will be reduced from 79 to 35, and the ratio of foreign shares will be further liberalized. The number of "joint ventures and cooperation" will be reduced from 43 to 11, "Chinese The number of "holding" entries has been reduced from 44 to 32. 
On the surface, there is a reduction in numbers, but analysts point out that the reduction in restrictions shows the government’s determination to actively expand its opening up and the market-oriented reform orientation. 
Wang Dong, inspector of the Foreign Investment Department of the National Development and Reform Commission, told the media that the revision of the Foreign Investment Industrial Guidance Catalogue was the largest revision in terms of reducing foreign investment restrictions, reducing share ratio restrictions and reducing share ratio restrictions. 
In fact, since the release of China’s first “Guidance Catalogue for Foreign Investment Industries” in 1995, it has been the sixth revised edition. The revised catalogue focuses on promoting the opening up of manufacturing and service industries, encouraging foreign investors to invest in modern agriculture, high-tech, advanced manufacturing, energy conservation and environmental protection, new energy, modern service industries, etc., encouraging foreign investment in research and development, promoting investment, Introduction and introduction of intelligence. The Catalogue clearly stipulates that all foreign-invested shares should be listed in the catalogue in principle, and the permitted projects are not subject to stock-to-share restrictions. 
Judging from the cancellation of the industry, the reporter found that compared with the "Catalogue" released in 2011, this time, some enterprises that have restricted the entry of foreign capital into high energy consumption and overcapacity have been canceled, such as the elimination of steel, ethylene, oil refining and other fields. Foreign investment restrictions. 
In addition, in the railways, subways, automotive electronics, lifting machinery, power transmission and transformation equipment, famous white liquor, international maritime transportation, e-commerce, finance companies, insurance brokerage companies, chain stores, land development, import and export commodity inspection, etc. Foreign investment restrictions have also been lifted.
Although the degree of openness is even greater than that of the Shanghai Free Trade Zone, there are concerns that the current domestic economic downturn and the domestic business operations are not optimistic, and the significant relaxation of foreign investment restrictions will have an impact on the development of domestic enterprises. 
However, most people in the industry do not agree with this concern. “Living the restrictions on foreign investment is a difficult and opportunity coexistence. Opening up is conducive to optimizing the industrial structure, which is conducive to enterprises to enhance their competitiveness and eventually go out.” 
Deputy Director of Guangdong International Strategy Research Institute In an interview with the reporter of China Sankei Shimbun, Secretary-General Liu Jisen also said that in the short-term, domestic enterprises may not adapt to the state of foreign competition, and it seems that the competitiveness of foreign investment is stronger, but in the long run The introduction of foreign investment is beneficial to the development of the industry. "If an industry is always protected by the government, it will have negative impacts and costs, which will affect its efficiency and motivation in technological innovation and competitiveness. It is actually a good thing to let foreign capital enter the competition. It can strengthen our enterprises. The crisis awareness.” 
The signal that is very obvious in reducing foreign investment restriction projects is to allow more industries to participate in free market competition. The new government has always advocated market-oriented reforms, and market-oriented reforms encourage fair competition, so the foreign companies are actually cancelled. Investment restrictions reflect the orientation of market-oriented reforms." Liu Jisen stressed. 
In his view, modern agriculture, high-tech, advanced manufacturing, energy conservation and environmental protection, new energy, modern service industry, etc. are the future development trends, but at present these industries are not developing ideally, and the driving force and competitiveness of the economy are not too Ideally, it is better to learn from the experience of foreign companies to promote the development of these industries. “The government now has some incentives to let go of some industries that have been restricted by the state because these industries already have the strength to participate in competition.” 
It can be seen that the liberalization of foreign investment restrictions is in line with the direction of market-oriented reforms and is also conducive to industrial upgrading. What domestic companies need to do is to participate, seize opportunities and meet challenges.
