Maintenance Labor Costs: Professional technicians are needed to monitor equipment status in real time and adjust virtual scene parameters to ensure smooth performances.

Content Update Costs: To maintain audience engagement, virtual scenes need regular iterations, continuously generating content production costs.

Cost Differences and Industry Practices:

Large-Scale Event Case Studies: The S10 stage alone invested 2 million yuan in its lighting system, with total costs potentially reaching tens of millions of yuan; the Spring Festival Gala XR stage reduced unit costs through resource reuse and economies of scale, but it still falls into the high-investment category.

Commercialization Exploration Case Studies: Second Grade Media invested 5 million yuan to build the industry's first XR group broadcast studio, with each visual chip and tracking system costing millions of yuan, indicating that the implementation of XR technology in the live streaming field still faces cost barriers.

Cost Reduction and Efficiency Improvement Paths: Companies like Leyard utilize digital solutions (such as LED immersive studios) to achieve a one-time investment, long-term operation model, gradually reducing costs. The application of multimodal motion capture and cloud-based compositing rendering technologies can improve resource utilization and indirectly reduce unit output costs.

Summary: XR stages have redefined the boundaries of stage art through technological integration, but their cost structure is characterized by "high hardware investment, strong technological dependence, and heavy reliance on content operation." Currently, the industry is still in the technological exploration phase, and cost optimization requires the substitution of domestically produced hardware, the establishment of standardized processes, and large-scale application. In the future, with the maturation of the metaverse ecosystem, XR stages are expected to achieve cost control through technological iteration and business model innovation, promoting the widespread development of virtual-real fusion experiences.
