So the idea of a globalised art market should be taken with a pinch of salt. In any case, it is a little premature for Western and Chinese readers to be finding their bearings in an analysis of the global art market that is bent on combining information from East and West at all costs. In order to provide a clear and transparent analysis for our entire global readership, this year our report is made up of an introduction that covers the results of art sales around the world in 2012, followed by two distinct chapters. The first of these concentrates exclusively on the art market in the West and Artprice data, while the second focuses on art in China and Artron data. This fertile relationship between Artprice and Artron has led us both to examine our areas of overlap and divergence and to look at the way a new geopolitics is evolving in the art market of the 21st century.thierry Ehrmann For the past ten year, Artprice has published its exclusive annual art market report - available in 6 languages -, which is distributed to over 6,300 media organisations and international institutions every year. Based on 6.3 million auction results from 4,500 auction houses around the world, the report contains macro- and micro-economic analyses providing the keys to understanding the annual evolution of the global auction market. It discusses the major trends in the market, analysed throughout the year on the ArtMarketInsight page of our website, by the Artprice press agency and jointly by the Artprice and the Art Market Monitor of Artron Econometrics Department. To complement this objective appreciation of the art market based on a year of global auction results, Artprice and the Art Market Monitor of Artron also offer numerous original rankings such as the Top 500 artists by auction revenue and the Top 100 auction results of the year.
