Abstract: With the deepening of supply-side reform, the contradiction between the demand and supply of rural public goods is becoming more and more prominent, which seriously restricts the implementation of the new rural economic construction strategy, so that strengthening the innovation of rural public goods supply system has become the core content of local government function transformation. In view of the problems existing in the local government supply of county-level rural public goods, the relevant subjects must change their ideas in time, clarify the causes of the problems, and take active and effective measures to seek the innovation path of supply system, so as to achieve the strategic requirements and construction goals of supply side reform.
