Research on The Statistical Measurement of Consumption Quality During the Covid-19 Pandemic

In 2020, the Central Committee of the Communist Party of China formally established the new development pattern of "take the domestic big circulation as the main body, the domestic and foreign double circulation" during the COVID-19 pandemic. Under the New Development Pattern angle of view, the consumption is the kinetic energy to turn "outside promotes the inside" to "inside promotes the outside". And the quality of consumption to a large extent reflects people's consumption. Consumption quality means that people's consumption is no longer limited to meet the most basic needs of life, but more attention to high-quality goods and service quality. With the improvement of consumption quality, people's physical and mental health develops more comprehensively, and social and economic development is more harmonious. In order to explore the growth of consumption quality, from the perspective of the new development pattern, we construct the consumption quality index system from four dimensions: The consumption quality of the consumer, the objective object of consumption, the external environment of the consumption society and the new development pattern, including 4 first-class indicators, 9 second-class indicators, and 15 third-class indicators. The factor comprehensive scores of consumption quality from 2001 to 2019 were obtained by principal component analysis.
