西北地区交通发展对旅游经济的影响

his paper picked the main provincial capitals on the Northwest Silk Road as an example, to analyze the coordination degree between the transportation system and the tourism economic system through the coupling coordination model. The following findings were concluded from the research: (1) From 2000 to 2016, the coupling coordination degree of the transportation and tourism economic systems of the major provincial capital cities in the northwest region was relatively low, all of the cities kept below the intermediate coordination level. (2) Xi\'an led the highest level of coupling and coordination during the period, Urumqi and Lanzhou improved from the serious imbalance degree to the mild imbalance degree. The coupling coordination degree between Yinchuan and Xining City has been increased slowly, they still stayed at the moderate imbalance degree. (3) During the period of 2000 to 2016, the coupling coordination degree of the major provincial capital cities on the Northwest Silk Road has become more stable. Except for the decline in the impact of the SARS epidemic in 2003, other years were growing. The development trend of transportation and tourism economy was consistent.
