解析：

1.在第1句中，“受经济发展的推动”表原因，可将其处理成原因状语，用分词短语driven by the economicdevelopment来表达;主语“到国外度假”可译为 goingabroad for a holiday 或 taking vacations aboard, 根据主谓一致的原则，谓语动词应用第三人称单数形式。

2.第2句中的“已高达”在汉语中跟名词的搭配比较随意，如“人数高达”、“金额高达”;译为英语时，“高”则需根据名词的单复数情况来选择相应的形容词，如此处搭配的outbound tourists(出境游客)为可数名词复数，故应译为 as many as。“高达 8300 万人次”可译为reached as many as 83 million。

3.第3句中的“逐渐”强调进行中的状态，可用现在进行时来表达;“习惯”用短语become/be/get used todoing sth.来表达。该句可译为 Chinese families are becoming used to taking vacations abroad。

4.在第4句中，“以便和孩子一同出游”表目的，可用不定式短语to travel with their children来表达，作句中的目的状语。

5.在最后一句中，因“力量”前已有修饰词“一支重要(的)”，故“海外购物的”宜处理成介词短语作后置定语，译为 a significant force in overseas shopping。
