Gu Shengzu, member of the Standing Committee of the National People's Congress and economist, recently said that adjusting the distribution relationship rationally, achieving balanced and shared growth and achieving priority for enriching the people are the biggest highlights and difficulties in the economic work during the "12th Five-Year" period.

Gu Shengzu pointed out that consumption "short board" is a prominent problem in the long run of China's economic development process, and it is the biggest obstacle to the long-term mechanism construction of domestic demand.

The key to crack down on the "short board" of consumption is to promote the reform of the income distribution system, realize the pformation of wealth from the rich to the rich, enrich the country and enrich the people, so that the people can "consume, dare to consume, and wish to consume".

In the relationship of income distribution, taxation is an important tool to regulate income gap and safeguard social equity.

Among them, personal income tax is the most closely related to the average wage earners, and has the most extensive impact. It has the function of benefiting the middle and low income groups and adjusting the high income group.

The biggest effect of personal income tax reform is to help improve the current imbalance of wealth distribution in China, and form an olive like distribution pattern of wealth so as to enlarge the proportion of the middle income class.
