According to the experience and policy orientation of China's preschool education system since the founding of the People's Republic of China, and comparing the development track of preschool education in developed countries such as Britain, America, France and Italy with that in developing countries such as India, Brazil, Mongolia and Cuba, it can be clearly seen that the public welfare trend of preschool education development in the world is accelerating; The number of countries and regions that implement free preschool education is expanding. The public welfare of preschool education determines that it cannot be provided completely through the market like commodities, but must be provided through the resource allocation mechanism outside the market. Therefore, with the further development of China's economy, the preschool education system in China in the future will be "public-oriented", "government-funded" and "county-oriented", and it will enter the "public-oriented period" with absolute advantages in quantity and quality, so as to prepare for entering the national compulsory education system and realizing free education for one, two and three years before school.
