The aim of the study is to explore the interaction effect of macroeconomics indicators, and working capital flows on financial performance in a developing economy. By using the static and dynamic approach of panel analysis, it has been shown that there is a relationship between the components of working capital and the gross profit and cash conversion duration. Second, while interest rates used as an interaction variable with the average payable days have adverse effects, firm performance would decrease if interest rates increase. The average payable duration extends; instead of primarily regressing, the average payable period positively correlates with firm performance. The conversion cycle of cash has a negative relationship, but it reverses its actions after using interest rate interaction. There is a negative relationship with gross profit in the simple regression exchange rate and cash conversion cycle while using the second interaction variable with the cash conversion cycle, has positive effects. In addition, the exchange rate gets higher to increase the cash conversion length, financial performance will be increased. In addition, the exchange rate gets higher to increase the cash conversion length, financial performance will be increased. This study receives new results, the exchange rate increases, companies that can pay early to payable will get higher firm performance while exchange rate and the interest rate have a significant role in changing the firm performance.

This paper aims to fill the existing gap by investigating the linkage between organic waste materials, financial development and renewables in Southeast Asia; this is the very first study covering this area. Using panel data of ten economies in this area in the period of 1990–2016 and estimating the advanced regression method in statistics of pooled mean group (PMG) estimates, the paper aims to examine the panel unit root tests in the first and second generations, as well as cointegration tests followed by Pedroni, Kao, and Westerlund tests; the results demonstrate that there is a negative impact from financial development on renewables. Further, biofuel processing is consistent with renewables that are predominantly made from organic matter and wastes. In addition, biofuel sources can be proxied by three factors, namely agricultural land, forest land, and number of heads of cattle livestock. The agricultural land has a negative and statistically significant impact on renewables while cattle livestock has a positive effect in the long run. Additionally, a higher level of trade openness has a lower level of renewables in the case of Southeast Asian countries.

The study aims to investigate the tail dependence between Chinese stock market and Vietnamese stock market in the context of the Covid-19 pandemic. Using the data on the Ho Chi Minh City Stock Exchange (VNI) and the Shanghai Stock Exchange (SSEC) representing for Vietnam and China stock markets, the study reveals the tail dependence across three periods including: pre-pandemic, during the chaos of the pandemic, and the period of adaptation to the pandemic. Using the copula method including Normal, Clayton, Plackett, Frank, Student, Symmetrised Joe-Clayton copulas, the research results confirm that there is no dependent relationship between the stock market between the two countries in the pre-pandemic. During the pandemic, the Vietnamese stock market is heavily dependent on Chinese stock market, especially the upper tail dependence. During the period of adaptation to the pandemic, this dependence relationship still exists but less than that in the pandemic.

This article uses a gravity model framework to examine the impact of green logistics on Vietnam's exports to countries participating in the Regional Comprehensive Economic Partnership (RCEP). The study uses a generalized least squares (GLS) estimation method based on panel data for the period 2010-2018 and has reliable sources. The results of empirical research have found the following main findings: (i) Logistics performance, encompassing cost, reliability, and time-related factors, significantly and positively influence Vietnam's exports; (ii) The interaction effects between supply chain input components (customs, infrastructure, and services) and CO2 emissions from the transportation sector have a positive impact on Vietnam's exports; (iii) The supply chain input components demonstrate direct and positive effects on exports when implemented in conjunction with their interaction effects with CO2 emissions from the transportation sector; (iv) The emissions of CO2 from Vietnam's transportation sector exert a negative influence on exports; (v) Adopting a green logistics approach that focuses on reducing CO2 emissions from the transportation sector demonstrates a positive influence on Vietnam's exports. This influence is observed through direct and moderating effects, indicating the potential for sustainable practices to foster export growth. These research findings provide valuable insights for managers and policymakers in the formulation of informed decisions related to the development and promotion of green logistics. By embracing sustainable practices and aligning export growth with environmental goals, Vietnam can enhance its competitiveness while contributing to a greener future.
