Over the last few years the SBA Office of Advocacy has funded several studies examining the patent activity of small businesses.
All show that small businesses outperform larger corporations in the issuance of patents on a relative basis, meaning that per employee or per dollar of revenue small businesses produce more patents than big businesses.
Today the SBA Office of Advocacy released another installment in this series. Innovation in Small Business: Drivers of Change and Value widens the scope of this research by looking at the effects of drivers of innovation - employee headcount, sales and R&D expenditures - on small business value.
The research was conducted by Ceteris, Inc. and uses patent production as a proxy for innovation. The use of patents as an innovation proxy is common in academic research. This is done because of the quality and accuracy of patent information and the lack of other relevant innovation data sets.
The key findings of the research are:
1. Innovation increases significantly as small businesses increase headcount.
2. Increasing R&D expenditures increases small business firm value.
Interestingly enough, the study also found that changes in a firm's sales have neither a positive or negative effect on innovation and there is no statistical relationship between patent count and market value.
Like all SBA funded studies, Innovation in Small Business is academic quality research using rigorous methods and detailed data sets. Studies like these are important in helping us better understand the role of small businesses in the U.S. economy.
And like other academic papers, it provides a literature review that covers past studies related to the research. I always find this section of academic papers to be extremely useful in understanding the broader topic.
The paper is available for download from the SBA Office of Advocacy.
