Correction: Wang, C.; et al. Postgraduate Education of Board Members and R&D Investment—Evidence from China. Sustainability 2019, 11, 6524

The authors would like to make the following corrections to the published paper [1]. The changes are as follows:

(1)

Replacing the email address of the fourth author:

[email protected]

with

[email protected];

(2)

Replacing the sentence in Section 4.4., “Robustness Test”, on page 12:

“The second stage regression shows the coefficient of a directors’ master’s degree is still significantly negative.”

with

“The second stage regression results are consistent with Table 5.”;

(3)

Replacing the sentence in Section 4.4., “Robustness Test”, on page 12:

“F statistics (F = 25.82) is greater than the normal threshold of 10, indicating our IV passes the weak IV test and has strong explanatory power to the endogenous variable.”

with

“F statistics (F = 24.80) is greater than the normal threshold of 10, indicating our IV passes the weak IV test and has strong explanatory power to the endogenous variable.”;

(4)

Deleting “in the IT industry” in the sentence of “Therefore, we used engagement in R&D work as the IV to test the robustness of our research results in the IT industry.” in Section 4.4., “Robustness Test”, on page 12;

(5)

Deleting “in the IT industry” from the Table 9 caption: ”IV 2SLS regression results in the IT industry” on page 12.

(6)

Authors would like to update the data in Table 9, so we need to replace the original

Table 9. IV 2SLS regression results in the IT industry.
