Overview

Global Expansion of Research and Development Expenditures

Global R&D expenditures over the past decade have grown faster than global GDP,[2] an indication of widespread efforts to make economies more knowledge and technology intensive. The global total rose from an estimated $522 billion in 1996 to approximately $1.3 trillion in 2009, with the rate of growth slowing in the 2008–09 recession years (figure O-1). Although the specific data points in figure O-1 are imprecise estimates, the steady and strong upward trend illustrates the rapidly growing global focus on innovation through R&D.[3]

R&D investments of Western countries slowed markedly in the face of adverse economic conditions. After 2008, R&D growth stopped and decreased for both the United States and the EU, after accounting for inflation. Growth for the Asian region (China, Japan, and the Asia-8) and the rest of the world slowed somewhat in 2008 and 2009, but from very high rates in earlier years.

The United States remained by far the single largest R&D-performing country, with an R&D expenditure of $400 billion in 2009. For the first time, the Asian region's total of $399 billion[4] matched the U.S. total in 2009 (figure O-2).

China's 2008–09 R&D growth increased by a record 28%—well above its 1997–2007 trendline growth of 22%—and propelled it past Japan into second place. 2010 data released by China's National Bureau of Statistics show a further 22% increase.

R&D expenditures can be viewed as long-term investments in innovation. The R&D/GDP ratio is a convenient indicator of how much of a nation's economic activity is devoted to innovation through R&D. A U.S. goal in the 1950s was to achieve an R&D investment of 1% of GDP by 1957. More recently, many governments have set their sights at 3% of GDP in pursuit of developing knowledge-based economies, a figure the EU has formally made its long-term planning target.[5]

However, decisions affecting the bulk of R&D expenditures are generally made by industry, thus removing achievement of such a target from direct government control. In the United States, industry funds about 62% of all R&D. The EU average is 54%, but with considerable range (e.g., nearly 70% for Germany, but 45% for the United Kingdom). In China, Singapore, and Taiwan, industry funding ranges from 60% upward. Nevertheless, government planners monitor the R&D/GDP ratio as an indicator of innovative capacity, even as few countries reach the 3% mark.

Over the past decade, many developing economies in Asia have exhibited increased R&D/GDP ratios; conversely, the United States and the EU ratios have broadly held steady. Japan's comparatively high R&D/GDP ratio reflects the confluence of contracting GDP and flat R&D.

China's R&D/GDP ratio almost tripled, from 0.6% in 1996 to 1.7% in 2009, a period during which China's GDP grew at 12% annually—an enormous, sustained increase. The gap in China's R&D/GDP ratio relative to those of developed economies suggests that there is room for China's R&D volume to continue to grow rapidly (figure O-3).

The decade-long (1996–2007) R&D growth rates of mature S&T economies were lower than those of developing ones. Growth of R&D expenditures in the United States, the EU, and Japan were in the 5.4%–5.8% range while growth ranged from about 9.5%–10.5% for Singapore and Taiwan, to 12% for South Korea.

The effect of the global economic slowdown on R&D expenditures is dramatic—a sharp drop in growth in most locations in 2008–09 that is in stark contrast to a 28% rise in China's R&D spending, its highest growth rate since 2000 (figure O-4).

The relatively greater R&D growth rates of Asian economies (excluding Japan) resulted in changes in the global distribution of estimated R&D expenditures. Compared to 1996, the North America region's (United States, Canada, and Mexico) share of estimated world R&D activity decreased from 40% to 36% by 2009; the EU's share declined from 31% to 24%. The Asia/Pacific region's share increased from 24% to 35%, Japan's low growth notwithstanding (figure O-5).

[3] These estimates rely on data from the Organisation for Economic Co-operation and Development (OECD) and the United Nations Educational, Scientific and Cultural Organization Institute for Statistics. They are not precise measures. Reported data are converted to dollar totals using purchasing power parities, the local costs of a standard market basket of goods and services. The accuracy of this standard economic conversion may degrade in the case of developing economies. In addition, estimation of some missing data and variable reporting mean that there is uncertainty about any specific point estimate. The reader's focus is directed to the overall trend, which reflects an internally consistent estimate over time.
