Résumé: This paper examines the evolution of startups in Algeria, including the obstacles and possibilities that influence the nation's entrepreneurial environment. Startups are significant catalysts for economic expansion, innovation, and job creation. Notwithstanding this considerable potential, entrepreneurs in Algeria have several problems, such as restricted access to financing, regulatory obstacles, a deficiency of skills, and inadequate infrastructure. The findings indicate that despite ongoing problems, substantial prospects for development exist, primarily through augmented government backing, the proliferation of digital technologies, and improved collaboration between startups and established companies. The report closes by recommending strategic measures to address current obstacles and provide a more favorable environment for startup growth in Algeria.

Résumé: The aim of this work is to show the importance and the role of the knowledge economy in the competitiveness of companies and the growth of national economies. The success of a Knowledgebased Economic Strategy (KBE) calls for creating an environment conducive to innovation and creativity that stimulates competition and guarantees intellectual and industrial property rights. Over the past few years, Algeria has adopted a development strategy based on the knowledge-based economy, to boost economic growth, and this must be further pulled out by highly knowledgeable sectors. After examining the various pillars of this New Economy, the article shows that despite the considerable efforts undertaken by Algeria, the expected results more particularly on a qualitative level have not been achieved. The level of knowledge competitiveness is even lower. The field of research and development is far from fulfilling the demands of competitiveness and integration within the knowledge-based economy because of the obsolete nature of the knowledge gained. Algeria must establish these efforts in this field, and that the state must play the orchestra role in that vision of the information economy.

La présence chinoise en Algérie entre investissement étranger direct et prestation de service Abstract: This article aims to study the nature of Sino-Algerian economic relations through, in particular, the analysis of investment over the period 2003-2015. Far from providing services in infrastructure and construction, the analysis shows that Chinese direct investment appears exclusively in the hydrocarbon sector where many partnership contracts between Sonatrach and the Chinese oil companies are realized. China's weak presence in the manufacturing sector in Algeria, an essential sector for the diversification of the economy, is now to be filled by the relocation of Chinese manufacturing companies to this sector, especially since the Chinese economy Is in full reconversion
