Abstract
Based on the characteristics of financial exclusion and income gap, this paper attempted to elucidate the fluctuation of China’s consumption rate through the mechanism of financial availability of low-income residents and its influence on household consumption in the reform era. The study showed that improving financial availability affects the consumption rate by increasing investment opportunities for low-income earners who can adjust the portfolio of composition. Meanwhile, this effect is affected by the income gap which plays a “threshold” role in the relationship between financial availability and consumption rate. Therefore, inclusive finance development must be adapted to economic development in order to prevent “too much finance”.
