Find new firms wherever the other firms are
If most programs aimed at encouraging entrepreneurship intend to provide affordable facilities proximate to supportive institutions and allied firms, my findings suggest that these programs should be fairly effective. As the Ordinary Least Squares regression models demonstrate, the number of existing firms in area proves the biggest predictor of new firm location in area. Presuming there is a causal relationship between existing firms and new firm generation, then any incubation facility located amongst a concentration of existing firms ought to be successful. Further, as new firm locations appear somewhat price motivated by lower rents, when considered in isolation, offering such affordable space in existing firm rich areas ought to ensure further success of the incubator approach.
What remains surprising about my findings is that the degree of urbanization seems not to matter. So long as firms locate in an urbanized area (>1,000 people per square mile), my findings suggest that whether the existing firm concentration occurs in a CBD or suburban office park fails to matter in its ability to attract new firms. Despite compelling arguments connecting urbanization and human capital to endogenous growth, these results seem to suggest that beyond a certain threshold, the degree of urbanization matters little. Or, as in the case of Research Triangle Park, new firms may even sprout in the woods, so long as there are other firms around to nurture them.
Opportunities for Further Study
Clearly, the spatio-‐economic factors driving firm location and formation behavior remains a fertile subject for further analysis. If the presence of existing firms in an area serves as such a strong indicator of new firm formation and location patterns, as determined in this study, the mechanisms by which firms agglomerate in the first place remain uncertain.
Further consideration of real estate market relationships and effects upon new firm behavior is needed. While the data utilized in this study provided a multi-‐ year picture of prevailing commercial market dynamics within Triangle ZIP codes, this data was nonetheless limited. Data for years before 2001 was unavailable, and not all ZIP codes had real estate market data for all years. A more comprehensive time series of real estate market conditions would prove invaluable to determining how these dynamics exert influence upon new firm formation.
Further, while the NETS is an invaluable tool for studying firm behavior over time, future studies within this subject area could do well to compare this historic data against self-‐reported behavioral data for new firms over the same time horizon. The ability to compare how new firms report their formation and location decisions against the behavior documented within NETS would undoubtedly provide rich insight into the needs, choices, and socio-‐economic factors important to new firms and ultimately, endogenous economic growth.
