Since 20-year reform and opening-up to the outside world, the private industry of Zigong has developed gradually, become more and more economically competitive, and played a more and more important role in the economic structure of Zigong. This paper analyzes the problems of private economy and its countermeasures based on the research on its status quo.展开更多

文摘The differences of regional economic development between underdeveloped areas and developed areas are mainly embodied by different levels of private economic development. Since 20-year reform and opening-up to the outside world, the private industry of Zigong has developed gradually, become more and more economically competitive, and played a more and more important role in the economic structure of Zigong. This paper analyzes the problems of private economy and its countermeasures based on the research on its status quo.
