Abstract: Elaborated in the paper is the present situation of export of China-made seamless steel tube products to the GCC market. Also analyzed are the statuses concerning the international seamless steel tube marketing competitiveness among China and other seven countries like Japan in the GCC market during the 2007—2018 period,based on the three aspects i.e., the market penetration rate, the revealed comparative advantage index and the quality premium value.Accordingly it is concluded that although China has taken the first place of seamless steel tube export in the GCC market in terms of scale,its product quality and product mix are inferior of those of its counterparts like Japan. Based on the current situation of the seamless steel tube industry in China,relevant suggestions are proposed to further sharpen the international competitiveness of China-made seamless steel tubular products in the GCC market,including,taking the domestic production equipment superiority to improve the product quality,and speed up the upgrade of the product mix;changing the marketing strategy to further extend the industrial chain; and enhancing the concentration level of the industry.
