为评价高速公路网状发展对国民经济效益的影响,提出一种基于投入产出的高速公路网国民经济发展乘数效应评价模型。分析高速公路网对国民经济贡献的测算理论,给出了高速公路网发展对国民经济的直接效益、前项乘数效益、后项乘数效益、消费乘数效益和就业、产业结构优化等效益贡献的测算模型和计算方法。研究表明,基于投入产出乘数效应评价模型,可以采用发展差异比较法和贡献率指数比较法来计算高速公路网发展对国民经济的贡献。
In order to evaluate the impact of expressway network development on the national economic benefits, this paper proposes an evaluation model of national economy development multiplier effect of expressway network based on input-output. This paper analyzes the calculation theory of the contribution of expressway network to the national economy, and presents the direct benefits to the national economy from the development of the expressway network, the benefits of the preceding multiplier, the multiplier benefit of the latter, the efficiency of consumption multiplier and the benefits of employment and industrial structure optimization Contribution calculation model and calculation method. The research shows that based on the input-output multiplier effect evaluation model, the development difference comparison method and the contribution rate index comparison method can be used to calculate the contribution of highway network development to the national economy.
