平台投资区块链满足一定条件将使出版商和平台都有所获益，本部分进一步研究投资区块链对购买正版产品消费者的消费者剩余（简称消费者剩余）与社会福利的影响。
Platform investment in blockchain technology, when certain conditions are met, will benefit both publishers and platforms. This section further examines the impact of blockchain investment on consumer surplus (abbreviated as consumer surplus) and social welfare for consumers purchasing legitimate products.
这一段给出了不同模式下消费者剩余和社会福利的具体计算公式。这些公式是基于消费者效用理论（对效用函数在有效估值区间上进行积分）和模型之前的均衡结果推导出来的。通过定义这些公式，为后续的数值比较和结论提供了定量分析的基础。
This section provides specific formulas for calculating consumer surplus and social welfare under different models. These formulas are derived based on consumer utility theory (integrating the utility function over the effective valuation interval) and the equilibrium results from the preceding model. By defining these formulas, a quantitative analytical foundation is established for subsequent numerical comparisons and conclusions.
通过数值分析（图3），研究揭示了一个关键矛盾：区块链投资总能提升社会福利（W），但区块链投资在特定区间会损害消费者剩余（CS）。这个矛盾在成本系数适中的“过渡区间”（0.371
Through numerical analysis (Figure 3), the study reveals a key contradiction: blockchain investment consistently increases social welfare (W), yet within a specific range, it diminishes consumer surplus (CS). This contradiction is most pronounced in the “transition zone” where the cost coefficient is moderate (0.371
矛盾的根源在于出版商定价策略的改变。在传统模式下（尤其是k
The root of the conflict lies in publishers' altered pricing strategies. Under the traditional model (especially when k
社会福利的提升，来源于供应链利润的增加额超过了消费者剩余的减少额。区块链通过消灭盗版，将原本被普通消费者通过盗版无偿获得的效用（这部分未计入社会福利），以及一部分正版消费者的剩余，成功地转化为了企业的账面收入和利润，从而提高了可量化的社会总福利。
The increase in social welfare stems from the rise in supply chain profits exceeding the decline in consumer surplus. By eliminating piracy, blockchain successfully converts the utility previously obtained free of charge by ordinary consumers through pirated goods (which was not accounted for in social welfare) and a portion of the surplus from legitimate consumers into corporate revenue and profits, thereby enhancing quantifiable total social welfare.
