装备承制单位是武器装备研制与生产的主体,合理限定同类装备承制单位的数量对促进武器装备建设具有十分重要的意义。为提高武器装备研制与生产的效率,针对我国装备承制单位之间竞争活力不足及数量确定不合理的问题,利用赫芬达尔-赫希曼指数(Herfindahl-Hirschman Index,HHI)测算同类装备承制单位保持竞争活力的数量,并以某型气象雷达装备承制单位数量测算为例,验证该方法的可行性与适用性。 The equipment-bearing unit is the main body for the development and production of weapons and equipment. It is of great significance to rationally qualify the number of units bearing the same equipment to promote the construction of weapons and equipment. In order to improve the efficiency of the development and production of weapons and equipment, aiming at the problem of the lack of competitive vitality and the unreasonable quantity determination of the equipment-bearing units in China, the Herfindahl-Hirschman Index (HHI) The number of units that maintain competitive vitality, and the number of units of a certain type of weather radar equipment, as an example, verify the feasibility and applicability of the method.
