To evaluate the R&D development in China, we can inspect both the R&D expenditure and the research talent pool. In this paper, we analyze the structure of the researcher groups by using dynamic shift-share analysis (DSSA). The DSSA results show that there is still much room to improve in the structure of research group. The provinces/municipalities from eastern China did not perform well in eng...

One of the corollaries of Ornstein’s isomorphism theorem is that if (Y, S, ν) is an invertible measure preserving transformation and (Y, S, ν) is isomorphic to a Bernoulli shift then (Y, S, ν) is isomorphic to a Bernoulli shift. In this paper we show that noninvertible transformations do not share this property. We do this by exhibiting a uniformly 2-1 endomorphism (X, σ, μ) which is not isomor...

QR algorithm for eigenproblems is often applied with single or double shift strategies. To save computation effort, double implicit shift technique is employed. In Watkins and Elsner[1], a higher-order shift strategy, generalized Rayleigh quotient shift strategy, is introduced. In this paper, we give a generalization of the double implicit shift technique for the higher-order strategy, and comp...

The unbalanced growth of employment among regions is ultimately attributed to the difference in industrial structure and competitiveness. At regional level, both shift-share EM1 EM2 models can realize purpose model, that is, thoroughly separate effects competitiveness on deviation. While expectation further achieve a complete separation deviation at model not competent, this precisely role mode...
