The absence of a Chongqing Union Recruitment is primarily due to the unique economic and administrative structure of Chongqing, China. Unlike other major cities in China, Chongqing operates as a municipality directly under the central government, which means it has a different approach to employment and recruitment services compared to other cities.

Chongqing's economic model is characterized by its heavy industry and manufacturing sectors, which are primarily state-owned. This state control over key industries has historically led to a more centralized approach to employment, where recruitment is often managed directly by the government or state-owned enterprises (SOEs). According to the China Statistical Yearbook, in 2020, state-owned enterprises accounted for 22.3% of the total employment in Chongqing, a higher proportion than in other major cities like Shanghai or Beijing.

The lack of a formal "union recruitment" system can also be attributed to the strong presence of SOEs in Chongqing. These enterprises often have their own internal recruitment processes, which are separate from the traditional labor market. This internal recruitment system is efficient for SOEs but does not align with the concept of a union recruitment that is common in other parts of China.

Furthermore, Chongqing's unique administrative status has led to a more localized approach to employment services. The city government, through its various departments, provides employment support and services directly to its citizens. This includes job fairs, vocational training programs, and direct employment opportunities through government projects. The Chongqing Municipal Bureau of Human Resources and Social Security reported that in 2021, they organized over 1,000 job fairs and provided employment services to more than 1 million people.

In conclusion, the absence of a Chongqing Union Recruitment is a result of the city's unique economic and administrative structure, which emphasizes state control over key industries and a more localized approach to employment services. This structure differs significantly from the traditional union recruitment systems found in other parts of China.
