“…There is a negative relationship between the turnover from the export of knowledge-intensive services and the export of medium and high technology products. This negative relationship can be better understood by considering the existence of a negative tradeoff between the export of services and the export of products [32]. • Turnover share SMEs: it is a variable that considers the share of turnover of small and mediumsized enterprises.…”

In this article we analyze the determinants and the export trend of European countries of medium and high technology products. The data were analyzed using various econometric models, namely WLS, Pooled OLS, Dynamic Panel, Panel Data with Fixed Effects, Panel Data with Random Effects. The results show that exports of medium and high-tech products are positively associated, among other variables, with the value of “Average Annual GDP Growth”, “Total Entrepreneurial Activity” and “Sales Impacts”, and negatively associated with, among other variables, “Human Resources”, “Government and Procurement of Advanced Technology Products” and “Buyer Sophistication”. A cluster analysis was realized with the k-Means algorithm optimized with the Silhouette coefficient. The result showed the presence of only two clusters. Since this result was considered poorly representative of the industrial complexity of the European Union countries, a further analysis was carried out with the Elbow method. The result showed the presence of 6 clusters with the dominance of Germany and the economies connected to the German economy. In addition, a network analysis was carried out using the distance to Manhattan. Four complex network structures and two simplified network structures were detected. A comparison was then made between 10 machine learning algorithms for predicting the value of exports of medium and high-tech products. The result shows that the best performing algorithm is the SGD. An analysis with Augmented Data-AD was implemented with a comparison between 10 machine learning algorithms for prediction and the result shows that the Linear Regression algorithm is the best predictor. The prediction with the Augmented Data-AD allows to reduce the MAE by about 0.0022131 compared to the prediction with the Original Data-OD.

“…There is therefore a positive relationship between exports of knowledge-intensive services and the presence of high-level scientific publications. This relationship stems from the fact that if a country is positively oriented towards technological innovation and research and development then it also has a growth in exports of knowledge-intensive services and a high level of high-quality scientific publications [23]. • Turnover Share SMEs: is the share of turnover of small and medium-sized enterprises in total on the value of the overall turnover of the economy.…”
