什么是“赢家通吃”与平台垄断？
What are “winner-take-all” dynamics and platform monopoly?
数字平台因网络效应、数据壁垒和极低的边际成本，容易形成少数巨头主导（赢家通吃）。这引发对反垄断、数据可携带与互操作性的监管讨论。
Digital platforms tend toward winner-take-all dominance due to network effects, data moats, and near-zero marginal cost, raising antitrust debates over data portability and interoperability.

区块链与分布式账本如何可能改变信任机制？
How might blockchain and distributed ledgers change mechanisms of trust?
区块链以去中心化、不可篡改的账本记录交易，可在缺乏中央权威时建立可信协作（如跨境支付、供应链溯源），但存在能耗、吞吐量与监管不确定性。
Blockchain uses a decentralized, tamper-resistant ledger to enable trust without central authority (cross-border payments, supply-chain traceability), yet faces energy, throughput, and regulatory uncertainty.

平台经济的“双边市场”特征是什么？
What is the “two-sided market” feature of platform economies?
平台同时服务两类相互吸引的用户（如买家与卖家），一边用户增多会提升对另一边的价值，形成网络效应；平台常对一边补贴、另一边收费。
Platforms serve two interdependent user groups (e.g., buyers and sellers); more users on one side raise value for the other via network effects. Platforms often subsidize one side and charge the other.
