Innovation is considered essential to improving competitiveness and efficiency, thereby promoting economic growth in both theory and practice. This study analyzes the impacts of innovation, measured by the number of researchers, and the number of patents and trademarks, on economic growth. The results represent issues for consideration by policymakers dealing with sustainable economic growth. Besides the literature review, an empirical analysis was undertaken using the two-step system Generalized Method of Moments (GMM). Research data was collected through the World Bank"s database, with participants from 69 developed and developing countries between 2006 and 2014. Empirical results show that innovation, together with national openness, foreign direct investment inflows, and government expenditure on education, have directly and positively influenced economic growth. In addition, the study found a positive intermediate role for institutional quality and the spillover effect of foreign direct investment in promoting the relationship between innovation and economic growth. This study suggests that policymakers should focus on improving research and development activities, strengthening economic integration, attracting foreign direct investment, and extensively reforming the institutional environment to facilitate economic development. Contribution/ Originality:This study systematically explores the role of innovation in economic growth under the influence of institutional quality and foreign direct investment, using data from 69 developed and developing countries from 2006 to 2014.

This study investigates the effects of public debt and budget deficits on the sustainable economic development of developing countries, taking into account the role of control of corruption. The two-step GMM method was applied for unbalanced panel data of 59 developing countries from 2004 to 2015. The study found that public debt and the budget deficit had negative effects on sustainable development, while the effect of control of corruption was positive. Moreover, using interaction terms between control of corruption and public debt and budget deficit, respectively, empirical results showed that controlling corruption limited these adverse effects. Thus, if the objective is to achieve sustainable economic development, developing countries should not see raising public debt or maintaining budget deficits as a strategy for economic development. The study contributes empirical evidence to the theory of debt overhang, crowded effects, and institutional theory in the context of developing countries. The implications are also discussed in this paper.

The objective of this investigation was to evaluate the technical and financial effectiveness of the current intensive culture of white leg shrimp (Litopenaeus vannamei) in Tien Giang province, Vietnam. A survey was conducted from December 2021 to April 2022 to collect data from shrimp farms in the Go Cong Tay district, which is a planned area of this province for brackish shrimp farming. The results showed that, in terms of technique, most farmers have a lot of experience and a high level of application of science and technology. The average size of the culture pond (0.26 ha pond–1), stocking density (78.83 ind. m–2), survival rate (85.28％), FCR (0.26), and harvested shrimp size (58 ind. kg–1) were similar to other Mekong Delta provinces. There were significant differences in the incomplete water sedimentation and treatment ponds and the major use of groundwater for shrimp farming. In terms of finance, the mean yield was 12,345.97 kg ha–1 crop–1 and was higher than other provinces in the Mekong Delta. However, the mean profit and the total profitability were 17,575 USD ha–1 crop–1 and 0.38, respectively, which was lower than the previous year in the Tien Giang province because of the high input costs. The results of this study show the necessary requirements for the sustainable development of the model of intensive shrimp farming in Tien Giang Province, including (1) the complete rebuilding of the system of farming, water sedimentation, and treatment ponds; (2) the efficient solution for using the surface water; and (3) the support of local authorities, aiming to help farmers reduce input costs and increase profits.
