Decoding the Six Evolution Stages of Chinese Commercial Bank Structures

Vertical Three‑Level Architecture

Most Chinese commercial banks adopt a "head‑branch‑sub‑branch" hierarchy. The head office includes the shareholders' meeting, board, senior leadership and virtual committees, with leaders overseeing specific lines such as corporate or retail banking. First‑level branches manage provinces or municipalities, second‑level branches sit below them, and sub‑branches (including first‑ and second‑level sub‑branches) operate at the grassroots level.

Horizontal Division: Segments, Lines, Business Units

Segment (板块) : Top‑level grouping by customer type or major business category; strategic, resource‑focused, not independently profit‑centered. Example: Retail Finance, Corporate Finance, Capital Markets.

Line (条线) : Vertical management system spanning head office to sub‑branches; standardized, professional, responsible for policy transmission and risk control. Example: Corporate Loan Line, Retail Risk Management Line.

Business Unit / Division (事业部) : Relatively independent profit‑center with its own P&L, authority over budgeting, product development and risk management. Example: Credit Card Division, Private Banking Division.

Key Distinctions and Common Misunderstandings

Line vs. Department : Departments are static functional units, while lines are dynamic management pathways linking head‑office departments to branch counterparts.

Division vs. Line/Department : Divisions enjoy greater autonomy, independent accounting, and full‑chain responsibility, unlike traditional lines that remain part of the bank’s overall structure.

Large Retail Segment vs. Retail Line vs. Retail Division : The segment is a strategic umbrella for all retail products; the line is the management channel; the division is an operational entity with its own profit‑center status.

Trends and Development Directions

Recent reforms show a reversal from division‑centric models back to segment‑based structures. Examples include Ping An Bank’s 2024 elimination of six industry divisions in favor of segment management, and Minsheng Bank’s removal of most industry divisions, retaining only micro‑enterprise and inclusive finance divisions.

Historical Evolution of Commercial Bank Structures

1. Functional (1980s‑1990s) : Departments organized by basic services; five‑level branch hierarchy (head‑office → provincial → city → county → savings office). Limited product range, low efficiency.

2. Flat (late 1990s) : Emphasis on service efficiency; reduced layers, removal of savings offices, empowerment of branch heads with personnel and credit authority; introduction of ATM and card systems.

3. Product‑Oriented (2000s) : Diversified product lines, front‑middle‑back office separation, specialized departments for corporate, credit, and risk management; launch of mortgages, consumer loans, and online banking.

4. Division‑Based (post‑2008) : Professional, differentiated business units (industry, client, product, platform divisions) to drive specialization; early pilots by Minsheng Bank, later adopted by Ping An Bank.

5. Matrix (recent) : Dual‑line management—day‑to‑day operations under regional branches, business guidance from division headquarters; large‑retail divisions become independent of non‑retail lines, branch heads focus on sales.

6. Agile (current) : Adoption of internet‑platform thinking; cross‑department agile squads, virtual banks without physical branches, technology‑driven core roles, rapid innovation cycles.
