3 Hunan Yujing Machinery Co.Ltd(002943) on March 25, the company said that it would focus on the main business of blood products in the future. It is understood that the pricing method of centralized purchase in the Guangdong alliance region is to take the lowest value for the price ratio between a single enterprise of a certain variety and the previous bid winning price. In addition, the centralized collection of Guangdong alliance is equivalent to volume linkage for blood products, which can be selected when it is not higher than the effective bid price and the national lowest online / winning bid price of the product. After the signing of the winning agreement, there is a guarantee for the basic number of people entering the hospital, which reduces and reduces the difficulty of secondary development of the hospital. The impact of this centralized collection on blood products is generally limited. In the follow-up, the company will also timely adjust its strategy according to the policies of each region.
