Abstract: Based on the BACI micro-trade database, this paper adopts the method of demand information regression inference to comprehensively measure the export product quality of China’s high-tech industries over the period of 1995-2013 from the three levels of overall, industry and product, then it makes a horizontal comparison with the major advanced economies and the emerging market economies. The result shows that: (1) the overall export product quality of China’s high-tech industry presents a periodical changing characteristics of “sharp rise-fluctuation shock” during the sample period, i.e., it firstly has a tendency of rising sharply between 1995 and 2004, then the phenomenon of alternative rising and falling even sharp fluctuations appears; (2) the product-level study indicates that the export quality of China’s high-tech products generally shows a sign of improvement, but the pace of improvement in recent years has slowed down. (3) the industry-level study indicates that the export product quality of almost all of the high-tech industries shows significant fluctuation characteristics during the sample period, the export product quality of some of the industry declines in varying degrees, while the export product quality of other part of the industry shows a upward trend in the twisted fluctuations. (4) the cross-border comparison shows that the export product quality of China’s high-tech industries stays at the middle or lower reaches compared with the advanced economies, there is still a big gap between China and the USA, Japan and Germany; but compared with the emerging market economies, the export product quality of China’s high-tech industries is superior to that of India, equivalent to that of Mexico and Brazil, but always lags behind Russia and so on.

Key words: high-tech industry; export product quality; advanced economies; emerging market economies
