Table 8 Main results with all coefficients. The main results testing the three hypotheses are provided with all the control variables and their estimated coefficients. All the distance variables are multiplied by − 1 in the regression to allow their interpretation as proximity. Hence, the positive coefficients of the distance variables mean proximity improves innovation performance
