交通运输行业作为基础性、先导性、服务性行业,与宏观经济发展有着密切的联系.在新的大部制背景下,亟需一个能够全面、及时、准确地反映交通运输经济与宏观经济之间相互关系的综合性指标.研究基于TSI指数构建了中国运输服务指数(CTSI),并结合相关性分析、周期性分析、重大事件影响分析对其进行合理性检验.相关性分析结果显示,指数与工业增加值之间存在较高的正相关性;经HP滤波处理的周期性序列对比显示,指数与工业增加值之间的周期性交化趋势基本一致,而指数出现波峰波谷的时刻领先于工业增加值约2个月;重大事件影响分析表明,指数能较好地拟合"非典"、国际金融危机等重大事件对宏观经济的影响.
交通運輸行業作為基礎性、先導性、服務性行業,與宏觀經濟髮展有著密切的聯繫.在新的大部製揹景下,亟需一箇能夠全麵、及時、準確地反映交通運輸經濟與宏觀經濟之間相互關繫的綜閤性指標.研究基于TSI指數構建瞭中國運輸服務指數(CTSI),併結閤相關性分析、週期性分析、重大事件影響分析對其進行閤理性檢驗.相關性分析結果顯示,指數與工業增加值之間存在較高的正相關性;經HP濾波處理的週期性序列對比顯示,指數與工業增加值之間的週期性交化趨勢基本一緻,而指數齣現波峰波穀的時刻領先于工業增加值約2箇月;重大事件影響分析錶明,指數能較好地擬閤"非典"、國際金融危機等重大事件對宏觀經濟的影響.

Transportation plays a basic, guiding and service role in society, which is closely linked with macroeconomic development. In the context of overhaul, a composite index is urgently needed to compre- hensively and accurately reflect the relationship between transportation economy and macroeconomy in time. The study constructed China transportation services index (CTSI) based on TSI index, combined with correlation analysis, periodic analysis and major event analysis to test the rationality. The correlation analysis shows that there is a significant positive correlation between CTSI and the industrial value added. The HP filtered cyclical sequence shows that CTSI and the industrial value added are almost coincident in trend, while the peaks and troughs of CTSI appear about two months earlier than that of the industrial value added. Major event analysis shows that CTSI can better fit the influence of "SARS" and the international financial crisis on macroeconomy.
