The Rebirth of China’s Securities Market: From Paper Stock Certificates to the Birth of the Shanghai Stock Exchange

#

If we trace the roots of China’s securities IT industry back far enough, we eventually discover that systems such as Jinzhen KCBP/KCXP and Hundsun AS/AR did not appear suddenly.

They were the inevitable results of decades of institutional evolution, driven by increasing transaction volumes, growing numbers of investors, and the need to manage increasingly complex securities data.

To understand brokerage trading systems, we must first understand:

Why did stocks appear? Why were shareholder cards created? Why did securities accounts emerge? Why did stock exchanges become necessary?

1. The Original Purpose of Securities Markets: How Can Companies Raise Capital?

#

Stocks were not originally created for speculation.

Their first purpose was:

Allow companies to obtain long-term capital from society.

Suppose a company needs 10 million yuan.

The traditional method:

Bank
 |
Loan
 |
Company

This is indirect financing.

Another method:

Investors
 |
Purchase shares
 |
Company receives capital

This is direct financing.

The securities market creates a connection between:

Social Capital
        ↓
      Shares
        ↓
    Enterprises

2. The Earliest Form of a Stock: A Paper Proof of Ownership

#

Originally, a stock was not a database record.

It was a physical certificate.

It represented:

A person’s ownership interest in a company.

For example:

Company Total Shares:

1,000,000 shares

Zhang San:

Owns 100,000 shares

= 10% ownership

The earliest securities system contained only:

Company

 ↓

Shares

 ↓

Shareholders

 ↓

Shareholder Register

The most important element was:

Shareholder Register

Because it answered:

Who owns how many shares?

3. The Foundation of Securities Markets Is Registration, Not Trading

#

When people look at today’s stock markets, they usually see:

Price
Charts
Buy Orders
Sell Orders
Transactions

It appears that the market is mainly about trading.

But from the perspective of financial infrastructure:

Trading is only the process.

The fundamental question is:

Who legally owns these shares after the transaction?

Therefore securities markets have two fundamental functions:

Trading

#

Answering:

Who sells to whom?

Registration

#

Answering:

Who ultimately owns the securities?

These later evolved into:

Exchange System

+

Registration and Settlement System

4. After 1949: China’s Modern Securities Market Disappeared Temporarily

#

After 1949, China’s mainland economy gradually moved toward a planned economic system.

Corporate financing mainly relied on:

Government Finance

Banks

Economic Planning

rather than:

Stock Markets

Capital Markets

Securities Trading

Therefore, when China rebuilt its securities market later, it was not simply upgrading an existing system.

It was rebuilding the entire market infrastructure.

5. Reform and Opening-Up: The Return of Joint-Stock Companies

#

After economic reforms began, China started experimenting with:

• Enterprise reform
• Joint-stock structures
• Social capital participation

This created a fundamental question:

After investors provide capital, how can their ownership rights be verified?

The answer:

Shares

+

Shareholder Registration

6. The 1980s: Stocks Returned as Paper Certificates

#

Early Chinese stocks were not database entries.

They were physical documents.

A typical certificate looked like:

+----------------------+
| Company Stock        |
|                      |
| Shareholder: Zhang   |
| Quantity: 1,000      |
| Certificate No: XXXX |
+----------------------+

The securities information system at that time was:

Paper Certificates

+

Shareholder Registers

+

Manual Records

7. 1984: Early Joint-Stock Experiments

#

Around 1984, China began experimenting with joint-stock enterprises.

However, this was completely different from today’s market.

There were no:

Securities Accounts

Trading Apps

Matching Engines

Electronic Brokerage Platforms

The process was closer to:

Company Issues Shares

        ↓

Investors Purchase Shares

        ↓

Receive Paper Certificates

        ↓

Company Records Shareholders

8. Transferability Created the Need for a Market

#

If stocks cannot be transferred, there is no real market.

Suppose Zhang San owns:

1,000 shares

and wants to sell them:

Zhang San

 |

1,000 Shares

 |

Li Si

The company can simply update its shareholder register.

But when there are:

100 shareholders

1,000 shareholders

100,000 shareholders

manual updates become impossible.

This creates the need for:

A centralized trading market.

9. Why Did Stock Exchanges Become Necessary?

#

A stock exchange solves several problems.

1. Concentrating Buyers

#

Buyers
   ↓
Exchange
   ↑
Sellers

2. Creating Unified Rules

#

Such as:

Price Priority

Time Priority

3. Automated Matching

#

Example:

Buy order:

10.00 yuan × 1,000 shares

Sell order:

10.00 yuan × 500 shares

Result:

500 shares matched

10. 1986: Shanghai Securities Counter Trading Emerged

#

Around 1986, Shanghai began developing securities counter trading.

The process looked like:

Investor

 ↓

Securities Counter

 ↓

Clerk

 ↓

Manual Processing

This became the origin of:

Brokerage branch counter operations.

11. Early Brokerage Branches Were the First Securities Systems

#

Modern brokerages have:

Customer Management

Account Systems

Cash Systems

Trading Systems

Settlement Systems

But early brokerage branches handled everything manually:

Customer Registration

Cash Records

Securities Records

Orders

Transactions

Settlement

Therefore:

Modern brokerage software is essentially the digital transformation of the old securities counter.

12. 1990: The Shanghai Stock Exchange Was Established

#

On November 26, 1990:

The Shanghai Stock Exchange was established.

It officially opened on December 19, 1990.

This was a major turning point.

China moved from:

Fragmented Counter Trading

toward:

Centralized Exchange Trading

13. The Securities Market Developed Into Multiple Layers

#

Investors

#

Question:

Who participates?

Brokers

#

Questions:

Who is the customer?

How much money does the customer have?

How does the customer trade?

Exchange

#

Question:

Did the trade execute?

Registration and Settlement System

#

Question:

Who finally owns the securities?

How are securities and cash delivered?

14. Securities Accounts: From Paper Ownership to Digital Records

#

Before:

Stock = Paper Certificate

After digitization:

Stock

↓

Securities Account Record

Example:

Securities Account:

A123456

Holdings:

600000 : 1,000 shares
600001 : 500 shares

The stock became a database object.

15. What Does a Shareholder Card Really Represent?

#

A shareholder card is not important because it is a physical card.

Its real meaning is:

Securities Account Number

It connects:

Investor

 ↓

Securities Account

 ↓

Registration System

 ↓

Share Ownership

16. Trading Seats: The Gateway Into the Exchange

#

The exchange could not allow every individual investor to connect directly.

Therefore:

Investor

 ↓

Broker

 ↓

Trading Seat

 ↓

Stock Exchange

The trading seat answered:

Who is authorized to access the exchange, and through which channel?

17. Electronic Transformation Made Brokerage Systems Complex

#

The early model:

Customer

 ↓

Branch Office

 ↓

Manual Counter

 ↓

Exchange

Later:

Customer

 ↓

Brokerage System

 ↓

Trading System

 ↓

Trading Seat

 ↓

Exchange

Eventually:

Customer

 ↓

Branch

 ↓

Centralized Brokerage Platform

 ↓

Trading Middleware

 ↓

Exchange

18. Why Did Centralized Brokerage Systems Become Inevitable?

#

Because brokerage networks expanded rapidly.

If every branch maintained:

Independent System

Independent Database

Independent Trading Connection

a brokerage with hundreds of branches would need to operate:

Hundreds of Systems

Hundreds of Databases

Hundreds of Interfaces

Therefore the industry moved toward:

Branch

 ↓

Head Office Centralized Platform

 ↓

Unified Trading System

 ↓

Exchange

19. The Evolution Path of Securities IT

#

The complete evolution:

Paper Stock Certificates

↓

Shareholder Registration

↓

Counter Trading

↓

Stock Exchange

↓

Securities Accounts

↓

Clearing and Settlement

↓

Electronic Trading

↓

Network Trading

↓

Centralized Brokerage Systems

↓

Trading Middleware

Eventually leading to:

Jinzhen KCBP/KCXP

Hundsun AS/AR

20. Conclusion: Software Was the Final Layer of a Much Longer Evolution

#

The history was not:

A software company created a trading system

It was:

Joint-stock companies emerged

↓

Stocks appeared

↓

Investors increased

↓

Trading volume increased

↓

Accounts became complex

↓

Settlement became complex

↓

Trading infrastructure evolved

↓

Securities software emerged

Therefore:

KCBP, KCXP, AS, and AR were not isolated software products. They were technological consequences of China’s transition from a paper-based securities market into a digital, networked, and centralized financial infrastructure.

The next chapter:

“1986–1991: How Did Shanghai Securities Counter Trading Actually Work?”

#

will reconstruct an early investor transaction flow:

Investor arrives at brokerage branch

↓

Provides identity and shareholder certificate

↓

Branch records account information

↓

Places order

↓

Brokerage processes order

↓

Trading seat sends request

↓

Exchange executes trade

↓

Settlement completes

↓

Ownership records updated

and map this historical workflow into the database tables, fields, messages, and communication protocols that later shaped modern Chinese securities brokerage systems.
