If you want to understand the theoretical underpinnings of my argument, I recommend these key works:

1. Cheng Enfu, On the Three Stages in the Development of Socialism

This directly addresses the point I raised about the long-term nature of the socialist transitional phase. Professor Cheng systematically outlines the developmental trajectory of socialism(from the primary and intermediate stages to the advanced stage)explaining why a ‘one-size-fits-all’ approach demanding absolute purity is unfeasible before productive forces have reached a sufficiently high level.

2. Cheng Enfu: Modern Marxist Political Economy

This book systematically expounds on how to scientifically utilize market mechanisms and capital to develop productive forces within a socialist framework, while emphasizing the state's need to firmly control the ‘economic lifelines’ (commanding heights) which is precisely the core logic of my earlier statement.

3. Cheng Enfu, Theory and Practice of Socialist Market Economy

This work provides a detailed argument for the objective necessity of retaining certain market-based elements and allowing non-public ownership sectors to serve as a supplement. From the perspective of political economy, it refutes the moralistic and naive view that the mere existence of private ownership or wealthy individuals means a system is ‘not socialist.’

4. Cheng Enfu, Socialist Political Economy with Chinese Characteristics

Provides an in-depth analysis of the dialectical relationship between maintaining public ownership as the mainstay and the common development of diverse forms of ownership. The book clearly points out that when productive forces have not yet reached a high level of socialization, forcibly eliminating all forms of small-scale production through administrative means runs counter to economic laws and leads to disaster, a point that perfectly echoes Lenin’s warnings in The Tax in Kind.
