The economic impact of Campania’s stadium renovations

Renovating a stadium is not just an architectural project — it’s an economic operation that creates jobs, income, and tax revenues. OpenEconomics has measured its impact through two key case studies.

When sport “renovates” the territory

According to a new economic impact study conducted by OpenEconomics, the renovation of sports facilities in Naples and Salerno will generate €457 million in GDP, based on €195 million in total public investment.

The project targets Campania’s two main stadiums: the Diego Armando Maradona Stadium in Naples and the Arechi Stadium in Salerno. Both will undergo modernization works over a three-year construction period.

Public investment and national economic impact

The study employs a multi-regional Italian Social Accounting Matrix (SAM) model, updated to 2022, to estimate the direct, indirect, and induced effects of public spending in sports infrastructure. The result: a spending multiplier of 2.49, with benefits spread across the national economy. This means that every euro spent yields €2.49 in economic value.

Key estimates:

• €457 million in GDP
• €204 million in tax revenues
• €452 million in household income
• Around 2,000 jobs created across several regions

• Lombardy: €73 million in GDP, over 300 jobs

• Apulia: €43 million in GDP

Focus: impact of each stadium

A closer look at the economic impact of each stadium’s renovation reveals significant differences:

Diego Armando Maradona Stadium in Naples

The renovation of the Maradona Stadium is expected to generate €235 million in economic impact, with:

• 1,200 jobs created
• €232 million in household income
• €104 million in tax revenues
• Over 35% of total impact located in Campania
  ‍

Arechi Stadium in Salerno

The Arechi Stadium renovation is estimated to generate €222 million,with:

• 970 jobs created
• €220 million in household income
• €99 million in tax revenues
