For formation of competitive advantage, related and supporting industries and the gyroplane industry is a relation of solidarity.

The airta对 Related and supporting industries of gyroplane industry including airport,aviation administration,aviation fuel and material support to the development of security business,as well as aircraft manufacturing and maintenance performance of relevant industries. (a)Auto gyro aircraft manufacturing. China's aviation manufacturing industry competition is more dispersed,and industry scale is very small,and enterprise efficiency is low,plus lack of national investment,long unreasonable structure of equipment and technology of the phenomenon is quite serious.In product structure,technological barriers and value-added lower proportion of ultra light aircraft model is in the majority. Our country imports most of its general aircraft,domestic aircraft lacking of proportion of 40%.At present domestic Auto gyro aircraft manufacturer's products used in the majority with multipurpose general aircraft,mostly used in aviation training,tourism,fire rescue,and other fields.Auto gyro aircraft used in business flight is relatively little. (b)Aviation parts and components manufacturing. Aviation parts and components manufacturing mainly includes aviation engine and airborne equipment manufacturing.Aviation engine is the core component of auto gyro aircraft.China's overall strength in aero engine is weak and thus the aircraft engine is one of the important factors restricting our aviation manufacturing industry. The domestic aviation engine technology lags behind and is of short service life. maintainability and poor competition strength.Besides military aircraft supporting domestic aero engine,civilian aircraft are generally foreign engine options. (c)Maintains. Domestic aircraft maintenance ability is not strong Pure domestic company are mainly concentrated in the field of airborne equipment maintenance,while high-end airframe and engine maintenance is given priority to foreign capital and joint venture. 82%of domestic companies focused on airborne equipment (components) maintenance,only 32 maintenance companies engaged in high profits and high technical content,accounting for 6%. 17
