Clarifying the export-markup nexus is particularly noteworthy and topical for export-oriented developing countries. Although intensive and extensive margins of exports help increase trade volume, the earned profit margin is small and decreases if firms export low-quality products or focus on processing exports. The markup represents a firm's market power: it also captures the evolution of price and costs affected by exporting. The estimation of markups facilitates the evaluation of the effects of various trade policies on market power.After China's accession to the World Trade Organization (WTO) in December 2001 and full integration into the global trading system, China exploited the East Asian production networks to become the 'World's Factory' and be the major exporter of information and communication technology products. Thus, an emerging topic warranting an empirical investigation is whether exporters also experience higher markups than their non-exporting counterparts in China, as predicted in theoretical models, for example Melitz and Ottaviano (2008) and Antoniades (2015).However, China's export activity demonstrates some specific features that may alter the exportmarkup nexus in the theoretical models, mainly ownership structure and trade content. International production fragmentation is an emerging and prevailing production pattern in the world economy. Cross-border production chains tend to include geographically proximate countries with trade integration (Johnson & Noguera, 2012). Through the appropriation of the advantages of favourable policies and cheap labour, China has attracted a large volume of export-platform foreign direct investment (FDI) from developed economies, especially its East Asian neighbours. Furthermore, foreign-invested enterprises (FIEs) play a critical role in China's export sector. For example, in 2005 and 2012, the proportion of total exports contributed by FIEs reached the high values of 58.3% and 49.2%, respectively.
