Gauging China’s influence on the world-IMF
In an article in the International Monetary Fund magazine ‘F&D’ (Finance & Development), Vivek Arora and Athanasios Vamvakidis discuss the ramifications of China’s opening-up policy. They said that the effects are well documented but even so, “the facts are astonishing”. From relatively poor beginnings three decades ago, the authors have said, China’s economy is now second in size only to that of the United States of America.
“Real gross domestic product (GDP) has grown by about 10% annually, implying a doubling every seven to eight years. The resulting 16-fold increase in a major economy’s national income during a single generation is unprecedented.”
China’s opening up has meant increasing linkages with the rest of the world, as reflected in its rising share in world trade, global markets for selected goods, and capital flows. China’s stronger linkages with the global economy have also led to a growing use of its currency, the yuan, abroad, as well as closer correlation of market sentiment in China and the rest of Asia and, more recently, the world. China’s share in world trade has increased nearly tenfold over the past three decades, to about 9 percent, while its share in world GDP has risen to 13% from less than 3%.
“The increase in China’s share of world trade is particularly striking in the markets for certain products. China now accounts for nearly one-tenth of global demand for commodities and more than one-tenth of world exports of medium- and high-technology manufactured goods. China’s rising share in world trade over the past three decades is underpinned by a rise in its share in the external trade of every major region (chart). China’s share is, perhaps unsurprisingly, largest in the trade of other emerging Asian economies (13%), and this share has seen a striking increase over time. But its share of African trade is almost as large, and its share in trade with the Middle East, the Western Hemisphere, and Europe has increased several-fold in recent decades.”
To quantify the effects of China’s growth on the rest of the world, Arora and Vamvakidis conducted an empirical analysis using data from the past few decades (the details are to be found in the paper this article is based upon). Shifting to the longer term, they estimated the impact on the rest of the world of long-term changes in Chinese growth, smoothing over the short-term fluctuations associated with the typical business cycle and focusing on longer-term fluctuations. Their results, based on data for the past two decades, suggest that a 1 percentage point change in China’s growth sustained over five years is associated with a 0.4 percentage point change in growth in the rest of the world (coincidentally the same amount as for the short and medium term).
