At the historic juncture where the "14th Five-Year Plan" is coming to an end and the "15th Five-Year Plan" is beginning, China’s construction machinery industry is accelerating its transition to a new form of productivity. Amid this transformation, the 2025 Changsha International Construction Machinery Exhibition will open grandly on May 15, 2025. During this time, the "Building a New Ecosystem, New Quality Toward the Future — 2025 (3rd) China Construction Machinery User Development Conference," organized by Tiejia Network, will also be held as scheduled. The conference focuses on user value and industrial upgrades, creating a deep dialogue platform between enterprises and users, and will introduce authoritative rankings in the construction machinery industry.
01 Under the Wave of Industry Transformation, User Demand Drives Ecosystem Reconstruction
Currently, global industrial chains are accelerating their reconstruction, and the waves of intelligence and green transformation are sweeping through the construction machinery field. The new generation of users is reshaping the industry ecosystem: they use digital tools for precise equipment management, promote "on-demand leasing" and other asset-light models, and have a surge in demand for intelligent control, low-carbon equipment, and remote operation and maintenance. The role of users is shifting from "equipment users" to "ecosystem co-builders," making them core participants in the technological innovation chain.
As China’s leading construction machinery user platform, Tiejia Network has always been committed to the mission of "serving users with dedication and promoting industry progress." This conference will gather global leading enterprises, pioneers in new energy and intelligent technology, and representatives from end users, to explore practical paths for empowering user value through new productivity.
02 Five Major Authoritative Rankings to Be Released: Defining Industry Value Metrics
The 2025 China Construction Machinery User Development Conference, as one of the key forums during the CICEE 2025 Changsha International Construction Machinery Exhibition, will release five major authoritative industry rankings, including the Excavator Retention Rate Ranking, "User-Selected" Product Popularity Ranking, Accessory Brand Popularity Ranking, Second-Hand Construction Machinery Dealer Ranking (Dealers/Brokers), and Influential User Ranking.

• Excavator Retention Rate Ranking: As the industry's first authoritative ranking centered on long-term value, it will become a core metric for assessing the market value and brand power of construction machinery products. It is one of the most valuable rankings in the industry. Based on over 100,000 real transaction data from Tiejia's second-hand machinery platform over 10 years, the retention price data is calculated based on the average condition of second-hand equipment, combined with an equipment residual value prediction algorithm (basic formula: second-hand transaction price / market price of new equipment in the same year) and market supply-demand fluctuation coefficients to ensure objective data that reflects the value changes of products over a three-year period.
  
• "User-Selected" Product Popularity Ranking: Using Tiejia's million-level user behavior data pool, a four-dimensional dynamic evaluation system ("attention + click rate + inquiry conversion + real-name voting") will be established, with data collected from PC, APP, and mini-program platforms to ensure an accurate reflection of real user preferences.
  
• "User-Selected" Accessory Popularity Ranking: The first ranking focusing on aftermarket accessories, based on real feedback from a nationwide pool of terminal users on the Tiejia platform.
  
• Second-Hand Construction Machinery Dealer (Dealers/Brokers) Ranking: A system to evaluate second-hand construction machinery dealers, creating an industry benchmark for honest business practices and reducing transaction information asymmetry. This helps high-quality service providers gain market premiums.
  
• 2025 Tiejia National Influential Elite List: Identifying benchmark users with both professional insights and industry contributions, constructing an industry knowledge-sharing ecosystem, promoting the widespread dissemination of technical experiences, and building a resource group of industry opinion leaders.
