Abstract: As the existing measurements of multidimensional polarization fail to reflect the correlation between dimensions, this paper introduces cosine similarity, and proposes a new multidimensional polarization measurement based on the relative deprivation theory. The method can also be decomposed statically and dynamically, and can analyze the contribution rate of each dimension and its change to multidimensional polarization. Using the data from China Family Panel Studies (CFPS), this paper empirically analyzes the multidimensional polarization between urban and rural households in China from four dimensions: income, properties, expenditure on transportation and communications, and educational level. The empirical results show that the long-term multidimensional polarization shows a significant downward trend, and the polarization effect of education, expenditure on transportation and communications, and income is the main reason, but the polarization effect of properties promotes multidimensional polarization.
