## 5 Research Conclusions and Countermeasures
### Countermeasures  
First, strengthen the recycling of agricultural film wastes and strengthen the supervision of local governments. In provinces where the agricultural film is lower than the threshold value, the use of agricultural film is far lower than in provinces where the agricultural film is higher than the threshold value. We can learn from the developed countries in Europe, who implement label management for the collected and processed waste agricultural film. \begin{table}

Enterprises are encouraged to purchase useful discarded agricultural film, and local governments can implement tax relief, financial subsidies, etc. for these enterprises. In order to avoid some enterprises only for tax relief and financial subsidies, local governments should strengthen supervision to ensure that useful discarded agricultural film can really play a role. Second, the recycling rate of agricultural film should be increased, and the use of plastic-free biodegradable films should be vigorously promoted. In provinces where agricultural film is higher than the threshold, governments at all levels should implement a recycling system for waste agricultural film. Local government should determine recycling times and methods and designate relevant enterprises to set up recycling stations in rural areas. Local governments and related enterprises should each bear a relative proportion of the recovery costs. The difference between the relevant enterprises' recycling cost and income can be supplemented by the local government with tax compensation policies to encourage enterprises and farmers to strengthen the recycling and utilization of waste agricultural film. With enterprises working as the main body and government as the auxiliary body, new technologies can be developed and innovated to produce fully biodegradable agricultural film using straw from various crops as raw materials. These fully biodegradable agricultural films should be able to degrade into organic fertilizers quickly after being discarded. In China, buying price of biodegradation films is maybe double/triple-fold higher than traditional agricultural film. The ecological environment has positive externalities. In the case of higher prices for biodegradable agricultural films, either the farmers are subsidized or the manufacturers who produce them are subsidized. Third, farmers' pesticide usage behavior should be restricted, and the insurance mechanisms used for protection against agricultural pests and diseases should be improved. Through knowledge and technical training, farmers are aware of the harm to the quality of agricultural products that is caused by large-scale pesticide application. We should promote the use of green pesticides. The technical staff of a pesticide sales station can provide targeted guidance to farmers on the scale and type of rational pesticide use.
