I am looking for information about the Auto Parts Manufacturing
Industry (usa and other countries) from various resources you can find:
These are the questions if possible I would like answered:

1.  The Industry's attractiveness and prospects for long-Term profitability 

2.  The Industry's Dominant Economic Features (examples:market size,
scope of rivalry, growth rate and what stage of the life cycle is the
industry in, number of rivals and their relative size, prevalence of
forward/backwards integration, channels of distribution, pace of
process and product technology change, to what extent are economies of
scale in purchasing,to what extent do learning curves exist, rates of
capacity utilization important for profitability, historical levels of
profitability)

3.  Segments within the industry? what are they, and how does their
presence affect firms, strategies, competition, and levels of
profitability within each segment?

4.Technological change, sociocultural and demographic changes,
political and regulatory changes, economic changes, and globalization
(or global changes).

5.Key Success Factors for Competitive Success
Do they all capitalize on economies of scale?  Is there an issue with
gaining access to resource providers and these firms have specific
contracts with them?  Are there specific technologies that allow these
firms to compete especially effectively?).

I can't offer much on the Business/economics aspects but in terms of
5)Key Success Factors for Competitive Success there is a burgeoning
service industry growing around them with business such as Auto Data
Network Inc providing software and services that make huge
contributions to profitability and efficiency.  They operate in USA
and UK see

Wouldn't it just be easier to ask your instructor, or perhaps go to
the library and do the research on this industry? For example, here
are a few good sources:
  "Motor Vehicle Parts and Accessories."  Encyclopedia of Global
Industries. Online Edition. Thomson Gale, 2005.(SICs: 3714) 2005
  "Motor Vehicle Parts and Accessories."  Encyclopedia of American
Industries. Online Edition. Gale, 2004.(SICs: 3714) 2004

Datamonitor Industry Market Research also has a wealth of information
about the domestic and international markets of the automobile parts
industry. Dun & Bradstreet is a good source for industry level
profitability and other key financial figures. NetAdvantage has a
wealth of information on the auto and auto parts industry. In short,
there is a wealth of information available in most local and
university libraries, such at the one at UCF.

BTW, you can use these same sources to find information on companies
as well, like say... Apple.

This looks like an academic assignment. Do you know the definition of
plargism and acadmic dishonesty.  I hope that you are not a student at
UCF, if so you may be taking MAN 4720 this summer at a regional campus
or next Spring after you return from your academic suspension.
