【摘要】：目前我国大多数城市对公交企业亏损都是采用政府和企业协商确定政策性亏损补贴的方法,这种方法不仅未能使公交企业因补贴而摆脱经营困境,而且使政府财政补贴负担反而越来越重。因此制定科学的城市公共交通财政补贴测算方法显得尤为迫切和重要。基于这种情况,应用经济学中的资源配置问题,将公交运营收入财政补贴和公交车辆改造财政补贴看作2种资源,并将其分别分配到道路交通和轨道交通中,然后根据线性规划的对偶理论构建城市公共交通财政补贴测算模型,并由线性规划的对偶理论揭示政府对道路交通和轨道交通的补贴单价为资源配置优化问题中线性规划模型的影子价格,也即对偶问题的最优解。最后以某市为例,验证模型的可行性。
[Abstract]:At present, most cities in our country are using the method of government and enterprise consultation to determine the policy loss subsidy, which not only can not make the public transport enterprise get rid of the operating predicament because of the subsidy. Therefore, it is urgent and important to establish a scientific calculation method of urban public transport financial subsidy. Based on this situation, the problem of resource allocation in applied economics is very important. The financial subsidy of public transport revenue and the financial subsidy of public transport vehicle transformation are regarded as two kinds of resources, and they are allocated to road traffic and rail transit respectively. Then, according to the dual theory of linear programming, the model of urban public transport financial subsidy is established. Based on the duality theory of linear programming, it is revealed that the subsidy unit price of government to road traffic and rail transit is the shadow price of linear programming model in the problem of resource allocation optimization. Finally, taking a city as an example, the feasibility of the model is verified.
