本研究结果发现垦丁地区之民宿业者基於其民宿行销特性，多选择较低花费之行销方式，且积极经营行销者为少数，网路行销工具之使用更不多见，然善於使用网路行销业者其经营状况大多良好，使用效益多属正面回馈，其成本低、传播速度快、多媒体丰富性高、互动性强，利用网路相关平台做为行销工具很切合业者简单又不高成本的要求。

An integral operator I(subscript n+p) defined by Hadamard product is introduced. Making use of this operator, the subclass S(superscript * subscript n+p) of p(superscript -) valent analytic function is defined in the open unit disk, the inclusion relation of S(superscript * subscript n+p+1)S(superscript * subscript n+p) and the best dominant function of differential subordination q1 are obtained. Furthermore, some conclusions are made according to the special parameters A and B.

用Hadamard卷积定义线性算子I，并利用算子I定义在单位圆内的解析的p叶函数类S(上标*下标 n+p)，给出了此函数类的包含关系S(上标*下标 n+p+1)S和微分从属的最佳控制函数q1，并根据参数A，B取不同的特殊值得出了相应的推论。
