Considering scenarios with and without green advertising, we compare the optimal solutions and performance of both green and non‐green manufacturers under three power structures. Green manufacturers who invest in green advertising experience enhanced output and profits, with the highest level of green advertising and profit improvement when they dominate market. In most cases, green advertising investment tends to decrease the output and profits of non‐green manufacturers. However, under specific circumstances, such as when non‐green manufacturers dominate market and the production cost of green products exceeds a certain threshold, investing in green advertising can unexpectedly stimulate demand for non‐green products.

绿色广告和权力结构如何影响绿色制造商和非绿色制造商之间的竞争？

考虑有和没有绿色广告的场景，我们比较了绿色和非绿色制造商在三种权力结构下的最佳解决方案和绩效。投资绿色广告的绿色制造商的产量和利润都得到了提高，当他们主导市场时，绿色广告和利润的提高水平最高。在大多数情况下，绿色广告投资往往会减少非绿色制造商的产量和利润。然而，在特定情况下，例如当非绿色制造商主导市场且绿色产品的生产成本超过一定门槛时，投资绿色广告可以意外地刺激对非绿色产品的需求。
