The great tour purchasing power is the drive power of promoting the region's tourism developmentln the regional space, scale economic and regional separation are one of the basic characteristics of promoting tourism industry, So we must arrange the regional tourism industry with a systematic method and give prominence to the central city. For its outstanding area in the regional space, central city has evident superiority in the regional ecnomic development, and has echelon between central city and its periphery scennic spots, which is the inducement mechanism of tourism industry's arranging, developing and advancing step by step. For the law of diminishing marginal utility and the theory of equilibrium, the max utility equilibrium of tourism consumption be at the point of tangency of undiscrepancy curve and the cost budget curve.
中心城市居民巨大的出游力是拉动其周边旅游地发展重要的内在驱动力;由于地缘关系,区域规模经济与地域分割并存,是旅游产业运动的一个基本特征,为此必须对区域旅游经济进行系统化布局,突出中心城市的产业中心性;因其区位条件独特,中心城市在区域经济发展中居于明显的优势,与周边城乡部位存在经济发展上的梯次性,这种梯次性是区域旅游生产力布局、产业发展梯次传动,最终整体联动的经济诱导机制;根据边际效用递减规律和旅游者最大效用均衡理论,旅游消费效用最大化的均衡在无差异曲线与开支预算线的切点(即旅游目的地选择的最佳位置)上,且随着边际效用递减,目的地选择的最佳位置向远离中心城市方向移动,这就是中心城市与周边旅游地互动关系的经济学解释。
