The paper tries to analyze the issue of human capital development on the performance of the organization at national and regional level, to identify and analyze, through the proposed conceptual model, the factors of the human resource development that lead to increasing the organization competitiveness by ensuring the connection between the specialized human capital and the organization performance, which will generate a competitive advantage over the selected organizations. The overall objective of the research focuses on the analysis of the existing links between the specialized human capital and the performance of the organization, the study and evaluation of the investment factors in the human capital within the industrial clusters, respectively the innovation and the entrepreneurial attitude in the industrial sectors of the North-West development region of Romania the context of increasing competitiveness. This requires an in-depth study of the impact of the human resources development on the achievement of increased performance within the clusters in Romania, as well as the influence of the cluster relations on the human capital within them. In Romania clusters have spontaneously formed as a result of international projects, as there has been no policy to stimulate the formation of competitive productive agglomerations. Cluster research focuses on the connection between the specialized human capital (training, education, qualification and training), cluster relationships (management, procurement, technology, innovation) performance of the organization (productivity, low costs, quality, innovation).Clusters in the North-West region of Romania capitalize on the interconnections between knowledge, resources, motivation, and relationships as central pillars of local development, providing information, specialized training, research, education and technical support. The factors of human resource development influence within clusters will need to be correlated with performance based on quantitative supplemental information that influences human capital efficiency, multivariate analysis of human captivity, resources, competitive advantage and relationship between them. The research is based on the assumption that human resource efficiency influences cluster performance. In this context, one can identify a conceptual level, which refers to the way we address the efficiency of human capital and performance, and an operational level, which refers to the concrete way in which we highlight them through measurement values. It was deemed necessary to select this factor in human capital development activities because the human resource is the essential element of a trading company, it is the central mechanism of any company, a financially stimulated element, which will implicitly lead to performance and high qualification of service / product achieved, aș well as strengthning the organization and its prestige. Within this human resources factor, labor force elements have been addressed as this is the main element of any internal "engine" of an organization that drives its activity and performance. The processing analysis of the data obtained and the interpretation of the research results were made using the programs SPSS 20.0 (Statistical Packages for Social Sciences) and Microsoft Office Excel, with which we obtained and produced graphs, correlations, analysis. Thus, for testing internal consistency, the measurement and fidelity of the 60 questions assigned to the components of knowledge management, human capital efficiency and competitiveness, investment in human capital, cluster relationships, and performance based on the Likert scale, the Croncbach Alpha(α) coefficient. Following the internal consistency test, a Croncbach Alpha coefficient of .916 resulted, indicating a high internal consistency of the quationnaire, which leads to its validity and will yield conclusive results. The association of the variables in order to highlight the correlation between them was based on the calculation of the correlation coefficient using the Pearson or Kendall tests. It is found that there is a good correlation between knowledge management and capital investment of .806, followed by performance .796, and with weaker relationship relationships within the clusters of .629. We can say that there is a strong link between investment in human capital and knowledge management, which leads to the interest in human capital development în the organizations, with the aim of achieving performance and increasing the competitiveness of the analyzed clusters. The analysis points out that the areas of human capital efficiency and competitiveness increase are correlated, having a coefficient of Sig. to <0.01, all of which are found to have average scores, ± 0.50 and ± 1, data showing that there is a strong correlation between them, the data being normally distributed. Different clusters of indicators were used and cluster comparisons were made by activity sectors, cluster members, catalysts, training institutions. The results indicate some progress towards a better competitive positioning, but participation in the human resource training has led to a qualitative leap in the development of organizations, especially in the furniture, IT and agro sectors. They also highlight some systemic weaknesses in the process of human resource development, driven by national training, R & D,and business, which require sustained efforts at multiple levels (entrepreneurial, institutional, economic, social, and political) to overcome the current stage and develop an open minded education of human capital in the near future. In the process of predicting the evolution of the factors for increasing the human capital efficiency, based on econometric methods models, it is assumed that the investment in human capital will continue to have a growing trend, within a foreseeable period of time, with the involvement of organizations, cluster members and correlated with the national and European legislative framework in force. In order to be relevant in establishing the organization's development strategy, the study of the implementation of knowledge management under analysis should be compared to market dynamics, activity and performance. If the market is more dynamic than the company, it will be noticed that the company will have a certain gap in terms of competition on the market. The role of statistical and econometric methods and models is considerably amplified in the context of market mechanisms as the complexity of the economic and financial activity of the organization increases, with profound implications in the management process, which cannot be achieved only on the basis of experience and routine, further requiring relevant studies and analyses to underpin operative and strategic decisions. In conclusion, the present study will provide, in an overall view, the image of identifying and outlining the relationships between knowledge management and human capital factors that lead to performance within the existing industrial clusters in the North-West region of Romania, whose connection leads to competitiveness.
