An Empirical Analysis of Income Inequality between a Minority and the Majority in Urban China: The Case of Ningxia Hui Autonomous Region

Based on the urban survey data of Ningxia Hui Autonomous Region in 2006, this paper studies the impact of ethnic characteristics on the income determination mechanism in the same economic region. Using the decomposition methods of Blinder and Oaxaca, Fields, and Morduch and Sicular, we analyze income gap between employed Hui and Han as well as income inequality within the two ethnic groups. The main conclusions are, first, that there is almost no income gap between Han and Hui in Ningxia. But different ethnic characteristics have effects on the income determination mechanism. Ethnic factors such as religion and social capital have no obvious effect on the income determination.Minority, Majority, Income Inequality

Parity space-based fault detection for Markovian jump systems

This article deals with problems of parity space-based fault detection for a class of discrete-time linear Markovian jump systems. A new algorithm is firstly introduced to reduce the computation of mode-dependent redundancy relation parameter matrices. Different from the case of linear time invariant systems, the parity space-based residual generator for a Markovian jump system cannot be designed off-line because it depends on the history of system modes in the last finite steps. In order to overcome this difficulty, a finite set of parity matrices is pre-designed applying a unified approach to linear time invariant systems. Then the on-line residual generation can be easily implemented. Moreover, the problem of residual evaluation is also considered which includes the determination of a residual evaluation function and a threshold. Finally, a numerical example is given to illustrate the effectiveness of the proposed method
