After the completion of the 6-meter-deep waterway regulation project in Wu’an section,10,000-ton river and sea ships can pass through Wuhan throughout the year,and the economic benefit of shipping is very significant.Taking bulk cargo as a representative ship,this paper scientifically evaluates the freight volume and ship structure of Wu’an section based on the statistical data of Wu’an section from 2018 to 2022 in accordance with the principle of “with and without ” and actual occurrence.On this basis,the quantitative calculation model of shipping economic benefit is built to evaluate the shipping economic benefit after the implementation of Wu’an section.It is estimated that in 2022,the shipping economic benefit of wu’an section bulk carriers will reach 484 million yuan,exceeding the expected target of the engineering design stage.The research can not only be used to determine whether the main economic benefit indicators of the project are realized,and provide an important reference for the post-project evaluation,but also help to guide the investment and management of waterway engineering projects,and provide a basis for promoting the optimization of relevant project plans and policies.
