Accession to the EU enabled Croatia to invest significant financial resources from the Cohesion policy to support its socio-economic development and catch up with more developed member countries. The availability of EU grants accelerated the recovery of public investments after their sharp decline following the outbreak of the 2009 economic crisis. In addition to the enormous financial impact, the Cohesion policy played a crucial role in changing the main features of public investments in Croatia. This chapter explores in more detail how the Cohesion policy has changed and is still changing the public investment policy in Croatia. Significant changes occurred in strategic planning, cross-sectoral and vertical cooperation, monitoring and evaluation. Numerous actors at the national and subnational levels had significant direct and indirect benefits from the Cohesion policy. However, putting new policy tools and approaches into practice and ensuring efficient spending of the available financial resources is anything but a simple exercise. On the contrary, implementing an ambitious and effective investment policy was challenging for the Croatian administration.
