The effectiveness of performance management will directly affect the overall performance of the enterprise, so the development of performance management is of great significance. But from the current situation, there are still some deficiencies in the performance management of many enterprises, leading to the actual role of performance management can not be played. Therefore, we should analyze and optimize the existing problems of enterprise performance management system.展开更多

However, with the prosperity of traffic, road traffic congestion and road aging problems have become increasingly prominent. The renovation project of old municipal roads has gradually become the focus of attention. The transformation of municipal roads is imminent. Therefore, we must strictly control the construction quality of the old road renovation project municipal roads, ensure the control and measurement of the old road renovation project municipal roads, and then improve the overall environmental level of the city, increase the residents' sense of belonging, and promote the rapid development of the urbanization process .展开更多
