Infrastructure and EU Regional Convergence: What Policy Implications Does Non-Linearity Bring?

5. Conclusions
- -
- Distribution of investment and support according to smaller regional units, i.e., NUTS 2 level. It would enable a more even development of infrastructure in regions. It might be appropriate to distribute the funds according to even smaller regions (NUTS 3 level). Still, due to the lack of data, conducting a study at this level is impossible;
- -
- Obligate countries’ governments to collect and publicly (in Eurostat) announce information on national and regional investments, broken down by their types. Provide a support budget (investment volume) for each type of critical infrastructure. It would allow for determining which investments in infrastructure development generate the most significant positive benefits;
- -
- Establish a tipping point, after which investments no longer generate positive economic outcomes for each type of infrastructure and control that assets do not exceed this threshold. When distributing national investments and support between regions, assess the distance to this threshold, and promote infrastructure development more intensively in regions with more significant gaps;
- -
- Establish the optimal level of infrastructure development that ensure convergence of regions for each type of infrastructure. It would allow EU investments to be directed to those regions that have not reached this level. Countries’ governments may develop infrastructure in regions where optimal development is achieved or exceeded. However, it should be financed from the national and regional budgets without support.
