Flypaper effect 捕蝇纸效果
The flypaper effect is a concept from the field of public finance that suggests that a government grant to a recipient municipality increases the level of local public spending more than an increase in local income of an equivalent size. When a dollar of exogenous grants to a community leads to significantly greater public spending than an equivalent dollar of citizen income: money sticks where it hits, like a fly to flypaper. Grants to the government will stay in the hands of the government and income to individuals will stay with these individuals.
