Before investigating the impact of RCBs founding on county capital allocation efficiency, it should be ensured that the capital allocation of whole economy and industries are efficient. I make preliminary correlation analysis between the logarithm growth of fixed asset investment and the logarithm growth of GDP or industries. Figure 2 plots the preliminary correlation results.In Figure 2, there are four panels (a), (b), (c) and (d). Panel (a) displays the correlation between the logarithm growth of fixed asset investment and the logarithm growth of GDP in sample counties. The rising trend line implies a positive correlation. A positive correlation between the investment logarithm growth and the logarithm growth of first industry is also found in panel (b). Similarly, the increasing trend line in Panel (c) indicates a positive association between the logarithm growth of fixed asset investment and the logarithm growth of secondary industry. Lastly, the upward trend line in Panel (d) reflects a positive association between the logarithm growth of fixed asset investment and the logarithm growth of third industry.
