People's Political Consultative Conference News（Reporter Liu Yang）“China has become the largest construction machinery manufacturing base and market in the world.，It occupies an important position in the world construction machinery industry structure.。However, there is still a core high-end hydraulic parts industry with poor technological innovation capability.、Low level of industrial cluster construction、The total number of technical personnel is insufficient.。”Not so long ago，During the Second Session of the 13th CPPCC Hunan Provincial Committee，Members of the CPPCC Provincial Committee from the scientific and technological circles submitted《On Accelerating the Development of High-end Key Parts Industry of Construction Machinery》A collective proposal。

Members of the scientific and technological circles of Hunan Province believe that，Changsha is the only city in the world with four top 50 construction machinery enterprises at the same time.，Be known as“Capital of Construction Machinery”，Its unique position and important influence in the construction machinery industry can not be ignored.，Changsha's deep industrial base and policy support also provide fertile soil for the technological progress and industrial upgrading of construction machinery.。

The committee members suggested in the proposal.，To build Changsha into an important national advanced manufacturing center、Building a world-class construction machinery industry cluster as an opportunity，Break through the shortcomings of core components and key basic materials of construction machinery，Lifting high-end hydraulic components、Independent R & D and manufacturing capabilities of key components such as gearboxes。Around the hydraulic part、Core common technologies and key areas of engine and sensor industries“Stuck in the neck”Technology，Increase investment in R & D and talents，Promote cutting-edge scientific and technological achievements in the industry and universities、Transformation of original scientific research achievements of scientific research institutes。

The commissioners also suggested that，Enhance the supporting and leading role of leading enterprises and build an independent supply chain system，Establish“Host enterprise—Parts and components enterprises—Raw material enterprises”Upstream and downstream collaborative innovation system of industrial chain of joint innovation；Establish a national innovation platform for high-end key components of construction machinery，Research and development of a number of international leaders、Mainframe and core parts products leading the development of the industry；Establish an effective market supervision mechanism，Specification host、Market behavior of spare parts enterprises and suppliers，Maintain the healthy development of industrial ecology；Guide and support key enterprises to integrate and apply emerging technologies to R & D、Production、Management and other links，Encourage and support the electrification of key mainframe enterprises、Hydrogen energy and other fields，Vigorously develop the international market。
