Film incentives attract attention because their immediate effects are visible: a production arrives, crews find work and suppliers receive orders. Assessing the policy takes us further. How much of that activity resulted from the support, and what did the public gain in exchange for its cost?
The purpose of public support
The answer depends first on the programme’s purpose. South Africa’s government distinguishes attracting foreign production from assisting local filmmakers to produce local content. These aims overlap, but they should not be assessed as though they were identical.

Spending may be a useful measure of activity. Sustained employment, business development and local creative expression describe other outcomes. A sound evaluation chooses indicators that reflect the stated aims, rather than allowing the most impressive number to define success.
Identifying additional activity
The next task is to establish what the support changed. If a production would have chosen the location anyway, its spending cannot all be attributed to the incentive. Economists therefore compare the observed result with a plausible estimate of what would have happened without the programme.
That estimate requires judgement and evidence. Changes over time, comparisons with other locations and producers’ responses can contribute to the analysis. Each has limitations, which should be made clear. Counting supported productions is a starting point; establishing the policy’s contribution is the deeper task.
Industry growth and the wider economy
California’s Legislative Analyst’s Office drew an important distinction in its 2025 assessment. It found evidence that tax credits influence production activity, while reporting weak evidence of a benefit to the state economy overall after accounting for alternative uses of revenue and displaced activity. The finding concerns California and should be read in that context.

A South African assessment would need the domestic programme’s costs, the activity it influenced and the conditions facing local businesses. International evidence can inform the questions and methods, while local evidence supports the conclusion.
The duration and distribution of benefits
The duration of a benefit matters too. A supplier’s first booking and a continuing commercial relationship have different implications. So do a short contract and experience that leads to further work. Evaluations should examine how opportunities are distributed and whether they extend beyond the supported shoot.
Public spending also involves choices. Training, distribution, local production and other sectors may offer alternative uses for the same resources. Comparing those options helps explain the case for a particular policy and the trade-offs it entails.
What would convincing evidence look like?
Convincing evidence connects the programme’s aim with its cost, additional activity, beneficiaries and longer-term outcomes. It explains the assumptions behind the comparison and identifies where the data remain incomplete.
The economic case for film support is strongest when its claims can be examined. A clear evaluation helps policymakers and industry participants understand what worked, where benefits accrued and what might need to change.
