Does the Export Product Quality Affect the Export Volume?

已有文献在解释中国对外贸易增长原因时,对出口质量因素重视不够。本文应用指数理论和价格分解模型构建了可比较的中国行业出口质量指标,从出口产品质量的角度来解释各贸易伙伴国从中国进口贸易增长的原因,对中国典型行业的出口质量对出口量的影响进行了实证研究。结果显示:中国行业出口质量在被考察国家中整体偏低,位于下游水平;中国不同行业出口质量的发展趋势不同,其中食品与活畜行业、化学品行业和以材料分类的制品业等的出口质量呈现上升趋势;中国行业出口质量的提升是各国从中国进口贸易占比增长的重要原因,这在中低收入水平的进口国家中体现得尤为明显。因此,中国提出的外贸发展从规模扩张向质量效益提高转变的战略具有一定的可行性和必要性。Academic literature hasn't attached enough attention to the export quality when they explain trade growth in China.Based on index theory and discomposition model of price,this paper builds a comparable index of export quality in Chinese industries.Meanwhile,it researches empirically the effect of export quality on export volumn in industries.The conclusions include:in the horizontal,Chinese lower export quality among sample countries in industries;in the vertical,different trends of export quality in Chinese different industries,the tendency of food and live animals,chemicals and related products,manufactured goods classified chiefly by material in these industries on the rise;the promotion of export quality in Chinese industris resulting counterpart countries' growth of import trade percentage from China,especially to lowmiddle income countries.Hence,the strategic target of central government,which is the translating development pattern of foreign trade from the expand of scale to the improvement of quality,is feasible and necessary.2014年国家社科基金项目(14BJL058); 2012年教育部人文社科项目(12YC790104); 2014年中南财经政法大学博士生国际化联合培养项目资
