Newly introduced legal mechanisms for investment development in Algeria under Law 22/18

 Investment constitutes a fundamental pillar for economic development and sustainable growth, particularly in developing economies seeking to diversify their sources of income. In Algeria, the legal framework governing investment has undergone profound reforms, culminating in the enactment of Law No. 22–18 relating to investment. This law aims to improve the business climate, enhance legal certainty, reduce administrative constraints, and attract both national and foreign investors. This article examines the newly introduced legal mechanisms under Law No. 22–18 through a critical legal analysis. It seeks to assess the extent to which these mechanisms effectively contribute to promoting investment in Algeria. Adopting an analytical and critical methodology, the study evaluates the legal guarantees, institutional reforms, and incentive schemes established by the new law, while highlighting their strengths and potential shortcomings. The article concludes that although Law No. 22–18 represents a significant shift toward a more investor-friendly legal environment, its effectiveness largely depends on proper implementation, administrative coherence, and the stability of investment policies.
