What are the advantages and disadvantages of decentralization?

Advantages and disadvantages of decentralization: (1) The government can handle local affairs more flexibly and according to local conditions. (2) Decentralized division of labor can prevent arbitrary and personal dictatorship of superiors. (3) The hierarchical management of affairs conforms to the democratic principle, which can give full play to the initiative of employees, stimulate their sense of responsibility and cultivate their ability to work independently. Disadvantages: (1) Too much local power can easily lead to localism and even ethnic division. (2) Excessive decentralization will inevitably lead to abnormal economic development across the country and aggravate the imbalance between regions. (3) the local authority is too large, and there are policies at the top and countermeasures at the bottom, so it is difficult to effectively implement the unified policies and regulations of the central government.
