摘　　要： 为了完善利用公路建设投资乘数计算公路投资对国民经济拉动效益的方法,针对目前利用凯恩斯乘数与投入产出法计算公路建设投资效益的不足,通过公路建设过程中投资乘数作用引起国民经济成倍增长的机理分析,提出从投资乘数的原始定义出发计算公路建设投资乘数的原理,推导了计算公路投资乘数时公路建设投资引起的边际消费的改进算法,并通过京石高速公路有关资料验证了该方法的效果;发展了基于投资乘数计算原理、现有公路工程投资测算、投入产出矩阵组合基础之上的应用方法,克服了常用算法用全社会的消费倾向代替公路投资消费倾向的不足。 Utilizing the highway investment multiplicator, authors aim to mend and develop a method to calculate the benefit of highway construction on the national economy increasing. Due to the insufficiency of KEYNES and invest-output methods, the authors analyze the increasing of national economy resulting from highway investment multiplicator, propose a theory of calculating highway investment multiplicator based on the original definition of investment multiplicator, and obtain an improved method to calculate the highway marginal consumption caused by highway construction investment. This method is approved to be effective after being tested by utilizing the data of Beijing-Shijiazhuang expressway. The major contribution of this paper is replacing social marginal consumption by highway marginal consumption via combining the multiplicator calculate and invest-output methods, as well as highway project budget as a whole.
