Adjusting stamp duty refers to a tax policy of the government to adjust the stamp duty rate. Stamp duty is a kind of consumption tax, which is applicable to all kinds of legal documents and financial documents. The adjustment of this tax rate will directly affect the market's enthusiasm for economic activities. The government's adjustment decision needs to fully consider the development of the market and economic expectations, so as to ensure the development of the whole society.

The implementation of stamp duty adjustment has different effects on enterprises in different industries. For the financial industry, the change of stamp duty will directly affect the development of various financial businesses such as trust, fund, tax payment and credit. For enterprises, stamp duty will also directly affect the signing of contracts and the declaration of consumption tax. Therefore, the decision to adjust stamp duty needs to take into account the interests of different industries and make reasonable adjustments.

Generally speaking, it is not a sustainable tax policy for the government to adjust social and economic activities by adjusting the stamp duty rate. On the one hand, this kind of policy is easy to cause excessive burden on customers, which affects the stability and development of the market, and at the same time, it is easy to evade taxes and other behaviors. Therefore, the government needs to find more scientific and effective tax policies to realize the harmonious coexistence of tax revenue and social benefits.
