文章使用Hoekman频度分析法对中国自由贸易协定的服务贸易壁垒水平进行测度,以期实证地描述其开放度的特征事实。研究表明:中国绝大多数区域服务贸易协定表现出显著的GAT=特征;三个频度指标计算出来的不同协定开放度排序存在一定差异;除教育服务外,国民待遇的开放度承诺均高于市场准入承诺;总体而言,协定的开放度并未出现和协定签署时间逻辑上的相关性,即签署时间越晚的协定开放度也越大;开放度最低的前三类服务分别为第12类“其他未包含的服务上”、第8类“健康相关及社会服务”和第10类“娱乐文化体育服务”。 The article uses the Hoekman frequency analysis method to measure the level of China’s free trade agreement on trade barriers, in order to empirically describe the characteristics of its openness. The research shows that most of China’s GATS shows significant GAT = characteristics; there are some differences in the sorts of openness of different agreements calculated by the three frequency indexes; except for educational services, the openness commitment of national treatment is higher than Generally speaking, the openness of the agreement did not appear to be logically related to the signing time of the agreement, ie the later the signing of the agreement, the greater the openness of the agreement. The first three types of services with the lowest degree of openness were the Class 12 “Other services not included”, Class 8 “Health related and social services ” and Class 10 “Entertainment and cultural sports services ”.
