A real estate investment trust is a company whose main activity consists of holding, managing, and enhancing a portfolio of real estate assets, often commercial spaces. In France, the largest of these, listed on the stock exchange under the SIIC tax regime, focus their investments on so-called “prime” assets: regional shopping centers, business parks in metropolitan areas, and high-end offices. This concentration directly shapes the geography of commerce and widens the growing gap between attractive territories and medium-sized cities that are falling behind.
SIIC Regime and Mixed-Use: What the 2026 Finance Law Changes
The regime for listed real estate investment companies (SIIC) allows real estate firms to benefit from a corporate tax exemption, provided they redistribute a large portion of their profits in the form of dividends. This tax framework influences portfolio choices: real estate firms prioritize assets with stable rental yields, thus prime locations in major urban areas.

The 2026 finance law, enacted on December 28, 2025, has extended this regime to mixed-use projects integrating at least 30% social housing. The goal is to encourage listed real estate firms to diversify their portfolios in response to the increasing commercial vacancy in certain formats (aging retail parks, peripheral shopping malls).
To follow real estate news on Conceze, this regulatory evolution marks a turning point in how lawmakers use taxation to guide the strategy of major real estate investors.

The extension to mixed-use does not guarantee automatic territorial redistribution. Real estate firms can meet the social housing criterion while remaining concentrated in metropolitan areas, where developable land is the most scarce and expensive. The system creates an incentive, not an obligation for geographic rebalancing.
Prime Assets and Territorial Inequalities: The Gap Between Metropolises and Medium-Sized Cities
Large French real estate firms direct the majority of their investments towards a limited number of metropolises. Lyon, Marseille, Bordeaux, Toulouse, and Île-de-France capture most of the capital flows dedicated to commercial real estate. Medium-sized cities, on the other hand, suffer from a double effect.
- Private real estate firms do not invest (or disinvest) in secondary city centers, deemed too risky in terms of vacancy and long-term rental yield.
- Local businesses lose their attractiveness due to the lack of renovation of premises, which accelerates vacancy and the decline of the commercial fabric.
- Local authorities, often facing budgetary difficulties, do not have the means to acquire and renovate abandoned commercial properties on their own.
The Action Cœur de Ville program and public initiative real estate firms attempt to fill this gap. These structures, supported by local authorities with the backing of the Banque des Territoires, buy vacant premises to install businesses or services. Their logic differs from that of listed real estate firms: they aim for territorial revitalization, not yield maximization.
The coexistence of these two models, private real estate firms on prime assets and public firms on fragile city centers, reflects a structural fracture. Public policies compensate for an imbalance that the private market amplifies.
ESG Performance of French Real Estate Firms Compared to European Standards
The pressure from institutional investors on environmental, social, and governance (ESG) criteria is changing the decision-making of large real estate firms. According to the MSCI report “Real Estate ESG Leaders Index Europe” from February 2026, French real estate firms like Gecina underperform compared to their European counterparts in terms of ESG adaptation. The lag is particularly evident in the decarbonization of commercial assets, a factor that weighs heavily on stock market valuation.
This underperformance has concrete consequences. A lower valuation premium means more expensive access to capital, which reduces investment capacity. Real estate firms that delay the thermal renovation of their assets risk seeing a portion of their portfolio become obsolete, especially due to the tertiary decree imposing gradual reductions in energy consumption.
Hybrid Spaces and Experiential Retail: The Case of Covivio
The Knight Frank study “French Retail Market Dynamics Q1 2026” documents a significant decrease in vacancy rates in shopping centers renovated by Covivio in Lyon and Marseille. The recipe: integrate hybrid spaces combining leisure, co-working, and experiential retail. Rents stabilized as early as the first quarter of 2026.
This model works for assets located in high-density areas well-served by transportation. It remains to be demonstrated that this approach can be transposed to medium-sized cities, where the catchment area does not always justify a heavy investment in repurposing.
What Public Policies to Redistribute Commercial Real Estate Investment
The extension of the SIIC regime to mixed-use is a first fiscal lever. Other mechanisms exist or are emerging to try to correct the territorial concentration of investments.
- Revitalization real estate firms, supported by public funds, allow local authorities to acquire commercial land and control its use in the long term.
- Solidarity commercial land, inspired by the residential real estate lease, is beginning to be structured to offer local businesses access to premises at moderate rents.
- Territorial conditionalities could be attached to SIIC tax benefits, requiring that a fraction of investments be directed towards areas facing high commercial vacancy.
None of these tools will be sufficient in isolation. The revitalization of secondary city centers requires a combination of incentive taxation, public land management, and adaptation of commercial formats. The French commercial real estate sector remains structured around a yield logic that mechanically favors metropolises. Changing this trajectory requires stronger regulatory constraints than those currently in force or sufficiently attractive incentives for large real estate firms to agree to geographically diversify their portfolios.
