Sub-RQ 2.2 was as follows: Is there a statistically significant relationship between SMEs’ reliance on crowdfunding and SMEs’ reliance on start-up funding?
4.3.2.1 Start-up funding, all years
The regression of crowdfunding on start-up funding was statistically insignificant, F(1, 998) = 2.560, p = .1099. The regression of crowdfunding on start-up funding had an effect size of 0.026, indicating that roughly 2.6% of the variation in crowdfunding could be explained by variation in start-up funding. The regression equation for the relationship between crowdfunding and start-up funding was as follows:
Crowdfunding % = (Start-up funding %)(-0.018) + 4.229
Thus, every additional percentage a company’s total finding from start-up funding reduced crowdfunding by roughly a tenth of a percent. The results of adding technology company status to the regression of crowdfunding on start-up funding are presented in Table 30 below, which also includes the results of the original regression.

Thus, technology companies received 3.261% more of their funding as crowdfunding, but the effect of being a technology company on outsourcing did not change start-up funding as a statistically insignificant predictor of crowdfunding as a % of total funding. The adjusted coefficient of determination of the regression of crowdfunding on start-up funding was 0.1099, but this regression did not meet the assumption of heteroskedasticity of errors through the Breusch-Pagan / Cook-Weisberg test, χ2 = 21310, p < .001. However, the same results were obtained through a RSE regression, so the findings reported above are statistically reliable.
4.3.2.2 Start-up funding, 2008
The regression of crowdfunding on start-up funding in 2008 was statistically insignificant, F(1, 98) = 2.330, p = .1302. The regression of crowdfunding on start-up funding in 2008 had an effect size of 0.0232, indicating that roughly 2.3% of the variation in crowdfunding in 2008 could be explained by variation in start-up funding in 2008. The regression equation for the relationship between crowdfunding and start-up funding in 2008 was as follows:
Crowdfunding %, 2008 = (Start-up funding %, 2008)(-0.030) + 4.360
Thus, every additional percentage a company’s total finding from start-up funding in 2008 reduced crowdfunding received in 2008 by roughly the amount indicated above. The results of adding technology company status to the regression of crowdfunding in 2008 on start-up funding in 2008 are presented in Table 31, which also includes the results of the original regression..

Thus, technology companies received 3.036% more of their funding as crowdfunding in 2008, but the effect of being a technology company on outsourcing did not change start-up funding in 2008 as a statistically significant predictor of crowdfunding as a % of total funding in 2008.
4.3.2.3 Start-up funding, 2009.
The regression of crowdfunding on start-up funding in 2009 was statistically insignificant, F(1, 98) = 0.080, p = .7779. The regression of crowdfunding on start-up funding in 2009 had an effect size of 0.0008, indicating that very little of the variation in crowdfunding in 2009 could be explained by variation in start-up funding in 2009. The regression equation for the relationship between crowdfunding and start-up funding in 2009 was as follows:
Crowdfunding %, 2009 = (Start-up funding %, 2009)(0.010) + 4.086
Thus, every additional percentage a company’s total finding from start-up funding in 2009-increased crowdfunding received in 2009 by roughly the amount indicated above. The results of adding technology company status to the regression of crowdfunding in 2009 on start-up funding in 2009 are presented in Table 32, which also includes the results of the original regression.

4.3.2.4 Start-up funding, 2010
The regression of crowdfunding on start-up funding in 2010 was statistically significant, F(1, 98) = 4.190, p = .0433. The regression of crowdfunding on start-up funding in 2010 had an effect size of 0.0410, indicating that roughly 4% of the variation in crowdfunding in 2010 could be explained by variation in start-up funding in 2010. The regression equation for the relationship between crowdfunding and start-up funding in 2010 was as follows:
Crowdfunding %, 2010 = (Start-up funding %, 2010)(-0.037) + 4.181
Thus, every additional percentage a company’s total finding from start-up funding in 2010 reduced crowdfunding received in 2010 by roughly the amount indicated above. The results of adding technology company status to the regression of crowdfunding in 2010 on start-up funding in 2010 are presented in Table 33, which also includes the results of the original regression.

4.3.2.5 Start-up funding, 2011
The regression of crowdfunding on start-up funding in 2011 was statistically insignificant, F(1, 98) = 0.290, p = .5893.

The regression equation for the relationship between crowdfunding and start-up funding in 2011 was as follows:
Crowdfunding %, 2011 = (Start-up funding %, 2011)(-0.038) + 4.897
Thus, every additional percentage a company’s total finding from start-up funding in 2011 reduced crowdfunding received in 2011 by roughly the amount indicated above. The results of adding technology company status to the regression of crowdfunding in 2011 on start-up funding in 2011 are presented in Table 34, which also includes the results of the original regression.
