In order to make the new recursive method convergence fast, the RLS-like forgetting factor is introduced to construct the new data Hankel matrices. In the framework of subspace methods, the gradient type subspace tracking method is used to implement the update of the state subspace, which results the unbiased estimate. Different from traditional offline method, the system matrices are recursively computed using RLS method. The convergence analysis of the proposed method is given and finally, the efficiency of this method is illustrated with a simulation example.A new closed-loop identification method is proposed to implement consistency estimation of closed-loop subspace identification.

Title :The Stylized Facts and Preliminary Tests on the Regional Income Disparityin China,1952-2002Abstract:Based on two recent sets of data on economic development in the Chineseprovinces over the 1952-2002period ,the paper generalizes several stylized factsand investigates the impact of structural change on the dynamics of regional disparitiesin China.We analyze the industry structure and property right structure in thelight of an econometric analysis of unconditional and conditional β-convergence.
