杭州承办世预赛票房破5000万，据估创10亿级别的综合经济效益（世预赛落户杭州票房超5000万，综合经济效益预计达十亿级）

Breaking down economic impact

I'm considering the ticket revenue of 50M RMB and its 10B RMB economic impact. I should illustrate how these multipliers work, like direct revenues from ticketing, accommodation, food and beverage, transport, as well as indirect and induced effects.

I should note risks of overestimating while discussing opportunities for the city, such as urban branding and sports industry growth. I need to clarify the statement about 1B-level effects, as it seems more realistic than the initial 10B estimate. A rough model might show 20x ratios as plausible.Creating a quantitative check

I'm working on a numerical analysis for potential attendance. If there are 2-3 matches with 40-50k attendees and 30-50% out-of-town visitors, with per capita spending of 1500-3000 RMB over a night or two, then I'm looking at around 66M RMB per match, potentially totaling 130M RMB for two matches.

I need to include hospitality and media operations spending, perhaps totaling 50-100M RMB. After applying multipliers and considering risks like double-counting and leakage, I can suggest ways to maximize benefits, such as fan zones and improved traffic management.Offering a calculation tool

I’m thinking about creating a quick spreadsheet calculator or a Python notebook to run some scenarios. As a coding agent, I want to ask the user if they’d like a calculator and what assumptions they want to include. I should be concise and helpful, so I’ll present my thoughts in bullet points.

I’ll summarize key points, provide rough calculations, outline methods and data needed for verification, note risks, and suggest actionable steps. Plus, I can offer to build a simple model or sheet if they’re interested!
