采用区位熵法将省级投入产出表转换为该省下辖城市投入产出表,然后以城市投入产出表为基础,编制城市交通运输业卫星账户流量表,定量测算城市交通运输行业对国内生产总值的直接贡献、间接贡献和完全贡献.通过以广州市为例进行测算,将测算结果与广州市统计数据、交通行业发展实际情况,及国外发展经验值进行对比分析,进一步验证了该方法的合理性和可行性.对于没有编制投入产出表的城市,假设研究对象城市与所在省份具有类似消耗结构的投入产出表,测算得到城市交通运输业对经济的直接贡献和间接贡献值,测算结果为交通运输行业科学管理与决策提供了依据.

本文从英汉比较的角度讨论汉语普通话"VP+看+S[+Q]"结构(即"看"字结构)中虚词"看"的句法语义。田源、徐杰(2017)提出,此类结构中的"看"已经语法化为间接问句标句词,本文认为相关语言事实并不支持他们的这一观点。本文指出,"看"与其后的疑问小句不构成一个成分;不能与"想知道、怀疑"等常选择疑问句作为其宾语的主句动词搭配;"看"出现时主句动词的形态受限制:可以是重叠式,但不能为光杆形式,不能后附"-了/过"等体助词。本文提出"看"不是间接问句标句词,而是尝试义助词。在句法上,它位于功能性中心语Moodt_(entative)位置,以IP为其补足语。内嵌疑问句初始位置为主句动词的宾语位置,经过外置操作,嫁接到Moodt_(entative)P之上,在表层语序上位于句子的右边界。本文分析可以解释为何"看"对于主句动词及其形态具有选择性,以及为何"看"之后多为疑问小句,不能为陈述小句,名词短语多不能出现在"看"之后。
