March 7，At the National Two Sessions in 2023，Deputies to the 14th National People's Congress，Chief Engineer of China Railway Industry、Deputy General Manager of China Railway Equipment、Wang Dujuan, chief expert, submitted relevant suggestions on the development of construction machinery.。She suggested，Implement a three-year subsidy policy for electric products of construction machinery，At the same time, the withdrawal management policy of old construction machinery should be clarified.。

As the world's largest producer and seller of construction machinery，Diesel consumption in the whole industry accounts for about one third of the national total.，The average emission of a high-emission construction machinery is equivalent to 30-Total emissions from 50 family cars，Some old construction machinery that has been used for a long time has more emissions.。According to statistics of China Construction Machinery Industry Association，The market ownership of major construction machinery products has exceeded 10 million units.，One of its Chinese emissions（Contain）There were nearly a million devices before.。

Diesel internal combustion engine has been used to provide power for construction machinery for a long time.，Relatively low level of emission technology，High energy consumption exists、Environmental pollution and other problems，It is estimated that，The total annual carbon emissions of construction machinery in China exceed 200 million tons.；Because there is no clear management policy for the elimination and withdrawal of old construction machinery.，A large number of old equipment can not be handled.，To construction machinery users、It brings great burden to enterprises and society.。

At present，The electrification of construction machinery in China is at a critical stage of development.，Leading enterprises in key technologies、Product development、Technical verification and industrial test、Some progress has been made in the construction of industrial chain.，The electric products of some enterprises have passed certain examinations.、Test、 Improve ，Begin to enter engineering application。However, at present, due to less usage,，The construction of industrial chain needs to be further strengthened，At present, the cost of electric construction machinery remains high.，The purchase price of users is more than twice that of similar internal combustion power construction machinery.，It seriously weakens the purchase intention of users.，Form“Good but not popular”Situation。

The electrification of construction machinery will promote the R & D investment and technological progress of power batteries, electric drive functional components and control systems.，Promote technological breakthroughs in related fields，It will contribute to the realization of construction machinery in China“Overtake on a curve”And“Lead the race”，Promote the green revolution in the field of global construction machinery。

Wang Dujuan suggested，We can refer to the way of subsidizing freight electric vehicles.，Follow“Who buys, who uses, who enjoys”Subsidy principle，Pure electric products purchased by users（Origin limited to the mainland of China，AndRVC＞60%）Subsidize。Subsidies are limited toT/CCMA 0001-2011《Definition and classification of construction machinery》Products listed in the Group Standard。Implement a three-year subsidy policy for electric products of construction machinery，Promote the electrification of construction machinery，It is expected that the sales of electric products in the industry will be greatly increased by 2025.，The three main products can achieve sales revenue of 42 billion yuan respectively.、20 billion yuan、10 billion yuan，The reduction of carbon emissions exceeded 1.64 million tons respectively.、1.46 million tons、1.17 million tons，It is estimated that the annual carbon emissions of the whole industry can be reduced by more than 4 million tons.。

At the same time，She suggested，Improve the registration system of in-service construction machinery，Classify and classify the construction machinery in stock，And promulgate corresponding regulations.，Eliminate the old equipment that does not meet the standard。Encourage the early withdrawal of old construction machinery，And give appropriate subsidies.。
