# Network Tower Sharing Analysis in Greece: A Structure-Conduct-Performance Approach
## 4 Discussion and Conclusions  
The proposed research implemented the SCP framework in the tower-sharing market in Greece. It is the first time the above-mentioned framework has been applied to the Greek telecom market, while results contribute to existing research on SCP implementation in telecoms. It should be noted that the SCP framework is applied in its extended form in a mature market to explain significant changes in market structure. Emphasis is not set on a linear one-way relationship between Structure-Conduct-Performance that can mainly contribute to explaining financial growth, but on potential feedback effects of SCP's variables, including also governmental policies. The analysis conducted revealed that the extended version of the SCP paradigm suits and provides valuable information (in strategic and decision-making level) regarding network tower-sharing in Greece, especially when it comes to interpreting the market structure's changes over time, especially focusing on the last decade. Results indicate that, as far as network tower-sharing is concerned, many variables exist that play a significant role. Namely, these variables include barriers to entry/exit, market concentration, demand rates in specific geographical areas, pricing policies, legal strategies, cooperation and competition strategies, investment strategies, and reinvestment of profits strategies. Government policies seem to be directly associated with operators' conduct and market restructuring. On the other hand, only indirect effects on performance are detected. Moreover, the SCP framework reveals the perspectives of network tower-sharing in the Greek telecommunication industry, focusing on the main drivers of TowerCos' emergence, as follows:  
1. Lower cost structure: TowerCos' involvement seems welcomed by alternative operators since the infrastructure cost is decreasing while the profit margins can be sustained. Moreover, such an involvement facilitates the implementation of next generation networks alongside developing new innovative services for their customers. Finally, competition is expected to increase among service providers. 2. Efficient network expansion: TowerCos' involvement improves operators' presence in areas where less or no revenues are expected. Such an element is important when it comes to 5G expansion, since better quality of service and faster speeds are expected in a wider range. 3. Efficient network expansion: Entry barriers are lowered since no passive infrastructure cost exists for both existing and new service providers. Moreover, entry costs are reduced to those linked to active infrastructure, enabling faster time to market for service providers. 4. Growth in data traffic: Internet-wide usage led to growth of data traffic, while universal coverage became a necessity. TowerCos' involvement delivered a more efficient planning, especially in terms of high speed and low latency. Following an analysis of the Greek mobile market focusing on infrastructure-sharing strategies, we examined in the previous sections basic conditions, government policies, incidents, and behaviors of the last decade in order to interpret the interrelationships amongst S-C-P. However, this valuable experience of examining the past provides, in parallel, the ground for visualizing the future and the means to reach the country's goals in the form of clear policy recommendations for the next phase that the Greek mobile market is entering. It should be noted that Greece is perceived as an integral part of Europe, and therefore, the proposed recommendations for Greece could potentially address other EU peer group telecom markets, too. One of the key objectives for Greece and Europe is to accelerate the deployment of high-speed mobile and fixed broadband services by 2030. Ensuring low latency, ubiquitous connectivity, and seamless service delivery across Europe is essential for establishing a sustainable competitive advantage in the global market.
