Knowledge transfer is considered the efficient way to improve regional innovation, but relatively little is known about how the innovation efficiency of scientific and technological (S&T) talents is affected by knowledge transfer within institutional environment, particularly, limited studies carried out regional differentiation analysis. Using panel data from 30 provinces in China between 2005 and 2017, this article empirically tests the influence of the institutional environment on knowledge transfer and analyses its impact between knowledge transfer and innovation efficiency of S&T talents in China. The results show knowledge transfer can significantly improve both the scientific and the economic innovation efficiency of S&T talents. Moreover, the effects of knowledge transfer on the innovation efficiency of S&T talents in eastern, central and western China had heterogeneity. Formal and informal institutions play mediating roles between knowledge transfer and innovation efficiency of S&T talents. This study contributes to the literature by constructing an econometric model with identified variables to test the impact of knowledge transfer on the innovation efficiency of S&T talents in China, in addition, the equation about knowledge transfer was explored. The research findings are valuable to regional governments and policymakers; our empirical evidence helps to develop more efficient strategy and policy planning. [ABSTRACT FROM AUTHOR]

The effect of technological innovation on renewable energy development has drawn attention from scholars and policymakers. Based on a panel dataset covering 30 provinces in China from 2005 to 2017, the present study aims to examine how renewable energy technological innovation (RETI), represented by patent stock considering the decay and diffusion of renewable energy technologies, promotes renewable power generation (RPG) by nonspatial and spatial econometric models. The results indicate that 1) a 1% increase in the RETI level of a particular province, on average, leads to a 0.411% increase in RPG in that province directly and a 3.264% increase in RPG in its neighboring provinces through technology diffusion; 2) the effect of RETI on RPG will be underestimated by 12.7% if the decay and diffusion of technologies are not considered; 3) the estimation coefficients of RETI are insufficiently sensitive to the values of the decay and diffusion rates; 4) spatial dependence plays a vital role in exploring the impact of RETI on RPG, and this impact will be underestimated by 34.3% if spatial dependence is ignored. • Renewable energy technological innovation (RETI) contributes to renewable power generation. • Indirect effect of RETI on renewable power generation is 8 times greater than direct effect. • Coefficients can be underestimated if technological decay and diffusion are not considered. • Effect of innovation is not sensitive to the decay or diffusion rates.
