Please post...Thanks.
Dear BPSers:
I've collated responses to my recent query to BPS about industry data. Thanks very much to all who responded.

ORIGINAL QUERY
Specifically, I am interested in indicators of: 1) 4-firm
concentration ratios, 2) industry growth rates, and 3) industry size.
Other industry-level data would also be welcome (e.g., R&D
expenditures, capital expenditures etc.).
RESPONSES
- The census of manufacturing has the data you are looking for. There is also an updated set of industry codes.
- Compustat is another way researchers gather the data.
- We have WRDS
- If you have access to Data Monitor reports (found in our Business Source Complete database), they often publish industry-level data that provides growth rates, industry size, and more. My students are able to access this information for research each semester. It is often organized by NAICS code.
- Have you looked on the U.S. Census Bureau's website? http://www.census.gov/ I don't know if you'll find exactly 4-digit SIC codes or for all industries or for all years you listed, but you may find suitable approximations. Look under "Business & Industry" and then "Economic Census" on that webpage.
- For industry growth, size etc check the Annual survey of Manufacturers available from the Census Bureau. You will find 2000-2009 on the web site and later in hard copy in your Government Documents department at your library. Four-firm concentration ratios are a bit tricky as you need market share data by SIC code. You might check Standard and Poors industry surveys to see if it is in there. The last time I used the concentration ratio was in a 1991 JOM. We used the Trinet data which is no longer in existence. For R&D expenditures, capital expenditures etc. you may simply have to go into compustat and collect these data by SIC code and average them.
- I have used industry level data for some M&A research (US only firms) using Compustat. I had to do it manually as I could not find the data already aggregated.If you are able to download the Compustat data, it is not that difficult to compile into 4, 3 or 2-digit code aggregates, including R&D and other data that you would likely find useful.
- I have used the IBIS World database to obtain some of the data. You might be able to get some information there.
- The U.S. Census Bureau conducts a "survey of manufacturers" every five years and they do compute CR4, CR8, etc. at 4-digit SIC code level (and possibly now for NAICS codes). I did find an annual survey of manufacturers that provides a great deal of information for NAICS codes.
- Go to the Bureau of Labor Statistics webpage (www.bls.gov) and search for Quarterly Census of Employment and Wages (QCEW). This dataset provides information on # of establishments, # of employees and total wages paid by industry, for the years 1973 onwards. You can use this data to compute concentration ratios and do any other industry analysis you want.
- Data on R&D, capital expenditures, employment etc. is available here: http://www.nber.org/data/nbprod2005.html
- You might want to consider using the PIMS Database, sponsored by the Stratagic Planning Institute. It has several advantages: 1. It supplies data by business units, or more specifically, by markets served, as the firms sees them. 2. All data is in ratios, thus avoiding overweighting responses by the biggest firms involved. 3. SIC ocdes are to the 6 digit form (at least the last time I used it). 4. Most data is averaged over a four year period, thus avoiding impacts of short-term trends. On the other hand, the firms are disguised, and the time periods do not necessarily match. Also, unless the system has been updated, you must use AQD as the statistical tool, which has some shortcomings that stem from its creator's philosophy.
- Data every five years is here, www.census.gov/econ/census07/www/data_release_schedule/whats_been_re leased.html (2007), and here, www.census.gov/epcd/www/concentration.html (1992 Census by SIC code is below 1997/2002). You can infer growth rates, of course.
