Chinese Manufacturing Enterprises And Knowledge Spillovers

Base on the data on three-digit and four-digit Chinese manufacturing industry, we hanve a case study on the human capital externalities within the industry and outside the industrial that the enterprise is in on the productivity of the enterprise, and compared the regression results of different ownership of enterprises. We find that, overall, human capital outside of industry has a positive externality on the enterprise productivity, but impact of human capital within the industry on productivity is weak, that is, Jacobs effect is significant positive, MAR effect is very weak; the productivity of state-owned enterprise almost free from the impact of human capital outside the enterprise; the relationship between non-state enterprise productivity and human capital outside the enterprise is same as the results of overall analysis.From 5 typical industry, the Jacobs effect in the leather products industry is stronger than MAR effect, but Jacobs is weaker than the average effect of strength; steel rolling processing industry, Jacobs MAR effect is stronger, which is consistent with the results of overall analysis; effect and MAR effects in electricity production industry are very weak; Jacobs effect in electronic device manufacturing industry is stronger than MAR effect, and Jacobs effect is higher than the overall results of the effect; Jacobs effect and MAR effects in Airlines and spacecraft manufacturing industry both are strong, with Jacobs effect is weaker than the result of electronic device manufacturing, but close to the result of overall analysis, MAR effect is much higher than the result of overall analysis.
