The Dynamics of Economic Policy and Regional Specialization: Evidence from China¡¯s High-tech Industry

Abstract: This paper investigates the effects of economic policy on regional specialization of China¡¯s high-tech industries for the period 1996 to 2005. Results indicate that the average level of regional specialization increases over years. Moreover, high-tech industry sector is highly localized in coastal regions. Using a dynamic panel data approach, we find that the implementation of high technology oriented export policy and subsidies for science and high technology activities encourage regional specialization, whereas local government¡¯s protections for local high-tech enterprises impede it. The empirical study also confirms the important role of high-skilled labor in determining regional specialization. Keywords: economic policy; specialization; high-tech industry; dynamics

Fermions Tunneling from Higher-Dimensional Reissner-Nordstr\"om Black Hole: Semiclassical and Beyond Semiclassical Approximation

Based on semiclassical tunneling method, we focus on charged fermions tunneling from higher-dimensional Reissner-Nordstr\"{o}m black hole. We first simplify the Dirac equation by semiclassical approximation, and then a semiclassical Hamilton-Jacobi equation is obtained. Using the Hamilton-Jacobi equation, we study the Hawking temperature and fermions tunneling rate at the event horizon of the higher-dimensional Reissner-Nordstr\"{o}m black hole spacetime. Finally, the correct entropy is calculation by the method beyond semiclassical approximation.Comment: 7 page
