摘要

我们研究了在标准化虚拟房地产市场中，新土地释放如何影响附近地块的定价。使用以太坊区块链上沙盒的9920个二级市场交易，我们围绕扩展公告实现了差异中的差异设计。附近的包裹在公告后会升值，并且影响随着距离的远近而衰减（在离散近定义下约为9 %；距离减半意味着价格约为2.2 %）。邻近资本随着发行规模的增加而减弱，但在品牌合作伙伴/名人浪潮中增强，并在市场范围内的突出事件中减弱（Facebook更名为Meta）。结果表明，在数字经济中，空间价值通过注意力驱动的网络外部性而不是物理访问来集中。

Capitalising the network externalities of new land supply in the metaverse

We investigate how new land releases affect the pricing of nearby parcels in a standardised virtual real estate market. Using 9920 secondary-market transactions from The Sandbox on the Ethereum blockchain, we implement a difference-in-differences design around expansion announcements. Nearby parcels appreciate post-announcements and the effect decays with distance (approximately 9 % under a discrete near definition; distance halving implies approximately 2.2 % higher prices). Proximity capitalisation weakens as release size increases but strengthens in branded partner/celebrity waves and wanes during a market-wide salience episode (Facebook rebranding to Meta). Results show that in digital economies, spatial value concentrates through attention-driven network externalities rather than physical access.
