With the rapid development of China's medical device industry, the medical devices manufactured in China have attracted more and more attention from the international medical market. The emergence of new materials and new technologies has played an extremely important role in promoting the rapid development of Chinese medical equipment abroad and meeting the challenges of the international market. However, some industry experts pointed out that the domestic medical equipment is still insufficient to compete with foreign-funded enterprises in terms of sustainable development of innovative capabilities.
"Although China currently has a research and development level that is synchronized with international development in medical device innovation technology, it is still unsatisfactory in application." Dr. Jiang Feng, vice president of the China Medical Device Industry Association, recently in the 68th China International The second medical device industry innovation and common technology forum held by the Medical Device Expo pointed out that China's medical device industry has strong development momentum and huge space, but it still has shortcomings, especially in the aspect of innovative technology. , The reality is very skinny. "
Import dependence is still high
At present, in the domestic medical equipment market, foreign capital and joint ventures have become the main force, and imported products have formed a sales monopoly in China. The reporter found in the interview that many people in the industry generally reflect that in terms of high-end medical equipment, medical institutions usually give priority to the purchase of foreign equipment. The executive deputy director of a hospital said that CT, MI, MRI, etc., almost no domestic products in medical institutions, basically monopolized by imported products.
Public information shows that China spends hundreds of millions of dollars in foreign exchange each year to import a large amount of medical equipment from abroad. Nearly 70% of the domestic high-end medical device market is divided by companies in developed countries. The medical equipment markets such as nuclear magnetic, MR, CT and so on are mainly concentrated in GE, Siemens And foreign companies such as Philips. In the field of medical electronic products in China, 90% of the ECG market, 80% of the mid-to-high-end monitor market, 90% of the high-end multi-channel physiological recorder market, and 60% of the sleep chart market are occupied by foreign brands, and domestic products It mainly focuses on low value-added types such as massage appliances and blood pressure measuring instruments.
In addition to exporting products, multinational companies also acquire domestic market shares by acquiring domestic enterprises, and set up headquarters and research centers in China to further develop the Chinese market. In August this year, Medtronic, one of the world's largest medical device companies, just established the first innovation center in Shanghai, except Europe and the United States. Medtronic stated that the establishment of the innovation center reflects the company's determination to "localize". Philips is also investing US $ 54 million in Suzhou to build a medical imaging base dedicated to R & D and production of basic medical services in the Asia-Pacific region.
Jiang Feng said: "The added value of multinational companies' products entering China is getting higher and higher. This trend has been particularly noticeable in recent years. Moreover, multinational companies have not only transferred production R & D to China, but also started to conduct targeted second-hand based on the Chinese market. For this development, domestic companies must make major changes to see this change. "
In fact, there are two characteristics of the medical device industry that make companies very "tangled". Chen Xin, China ’s chief representative of the Global Medical Innovation and Capital Cooperation Organization, said that on the one hand, the barriers of the medical device industry are high, but the scale is often not large, and the profits are high; on the other hand, high profits are often accompanied by high risks, medical devices Industrial investment has a long return cycle, and the predictability from investment to exit is also a major problem. High investment and a long return cycle have discouraged many investors.
While domestic companies are still on the sidelines, the Chinese medical device market has become a nugget for multinational companies, and foreign capital is still entering.
"China's medical device industry has not yet formed a good R & D innovation environment and incentive mechanism. Industry development mainly depends on market self-regulation, especially the lack of government leadership and related support policies, resulting in government, enterprises, venture capital, scientific research institutions, colleges There is no coordinated development of the relationship between schools and other resources. "Chen Xin said.
