Abstract

This project work explores the world of input-output analysis, a powerful economic tool that reveals the complicated web of economic interdependencies that exist within a region or nation. By meticulously exploring the foundations, applications, and implications of this analytical method, we set out on a journey to understand the profound impact it has on economic systems. The project begins with a comprehensive introduction to the theory of input-output analysis, shedding light on its historical evolution and underlying assumptions. It meticulously outlines the step-by-step process of constructing input-output tables and interprets the matrix algebra involved, ensuring that even a novice can grasp the fundamentals. Two hypothetical case studies add practicality to the project, vividly demonstrating how input-output analysis can be applied to real-world scenarios, such as the infrastructure sector, the energy sector, and local economic development. Through these case studies, we witness the transformative potential of this analysis, both in terms of economic growth and sustainable practices. Furthermore, the project explores the strengths and limitations of input-output analysis, paving the way for informed discussions and decisions in the realms of economic policy and planning. In the end, the project leaves no stone unturned, presenting a comprehensive view of input-output analysis as a dynamic instrument that empowers us to unravel economic intricacies, fostering a prosperous and sustainable future.

Abstract

Since the early 2000s, digitalization and the digital economy have developed rapidly and rapidly changed all aspects of social life. Digital platform ecosystems in Vietnam are still in their early stages of development, but they are growing rapidly. These digital platforms are playing an increasingly important role in the Vietnamese economy. They are driving innovation, economic growth, and job creation. This article will analyze some of the current development status of the digital economic ecosystem in Vietnam: the advantages as well as the difficulties and challenges that Vietnam will face. The article will provide some policy suggestions for Vietnam in developing the digital economic ecosystem from these analyses.

Abstract

Heavy metal contamination of soil pose risks and hazards to humans and the ecosystem through. Imperata cylindrica is a fast growing plant and often used for phytoremediation. The plant was tested in different growth media of spiked heavy metal, soil pH and organic matter contents for 60-day. After harvesting, the plant was washed, separated into roots and shoots. The soil samples were digested using 1.0g portion of dried the soil ,10.0cm3 of 1:1 HNO3: H2O, 5.0cm3 of HNO3, 1.0cm3 of H2O2, and 5.0cm3 of HCl while the plant samples were digested using 0.50g of the powdered sample, 5cm3 of HNO3 and 2cm3 HClO4. Prior to digestion, each sample were oven-dried at 70°C until it achieved a constant weight, grounded (using mortar and pestle) and milled (using a milling machine). Atomic absorption spectrophotometry was used to analyze the accumulation of cadmium, and lead in roots and shoot of the plant. Bioaccumulation factor (BF), biological accumulation coefficient (EC) and translocation factor (TF) was applied to evaluate the metal translocation ability in the plant. Between soil pH and soil organic matter, the highest total biomass of Cd was found in 300g of organic matter treatment (13.48 ± 2.69 mg/kg), while Pb in basic treatment was 18.09 ± 0.66 mg/kg. The result suggests that soil pH has most effect on Pb; while organic matter in Cd in the phytoaccumulation by Imperata cylindrica. The growth of phytoremediation plants like Imperata cylindrica should be encourage to neutralize the heavy metals pollution.
