For the period as a whole, the nominal growth of large business GDP grew by 46% while small business GDP grew by 26%. You'll note the rapid growth of large business GDP in 2010; nearly 60% of the growth was due to one sector - finance (this was not a rebound from the crash but represented nearly a 30% increase from the previous peak).
Why the underperformance of smal businesses? One reason is construction, which represents about 10% of small business GDP, but only 2% of large business GDP. In addition, in several sectors, large businesses outperformed small businesses. For example, manufacturing suffered a significant decline in 2009 regardless of the size of the firm, but large business manufacturing declined by 6.4% while small business manufacturing declined by 15.5%. As manufacturing rebounded in 2010, large businesses grew by 6.9% while small businesses grew by 4%. Similarly, in wholesale and retail trade, small businesses declined at nearly three times the rate of large businesses in 2008-2009.
Which sectors are dominated by small businesses in terms of share of GDP? Construction (83%), Real Estate & Leasing (75%), and Arts & Entertainment (69%). Large Businesses dominate Utilities (nearly 90%), Information Services (88%), and Manufacturing (72%). Just over 13% of small business GDP comes from Wholesale & Retail Trade while just over 12% comes from Real Estate/Leasing and Professional/Technical Services, respectively. As of 2010, the largest shares of large business GDP are derived from Manufacturing (21%), Finance (15.6%), and Wholesale/Retail Trade (14%).
There's much more information available in the report. It confirms what most people already knew; small businesses are struggling as the economy continues to recover from the Great Recession.
