摘要

本文调查了COVID-19大流行对印度Greenex行业的影响。为此，本研究选择了印度Bomby证券交易所的BSE Greenex指数。采用对数法将日价格换算为日收益进行进一步分析。采用描述性统计、ADF检验、Q-Q图和GARCH(1,1)模型进行分析，结果表明，BSE Greenex指数为正收益，收益最高。ADF测试证实数据在水平差处达到单位根。该研究还发现，在新冠疫情期间，BSE Greenex指数波动较大。因此，该研究得出结论，在研究期间，COVID - 19大流行影响了印度的绿色行业。

Impact of Covid -19 Pandemic on Green Industry

The paper investigates the COVID-19 Pandemic’s impact on India’s Greenex industry. For this purpose, the present study selected the BSE Greenex Index from the BSE (Bomby Stock Exchange) of India. By using the logarithm to converted daily price into the daily returns for further analysis. Descriptive Statistics, ADF Test, Q-Q Plot and GARCH (1, 1) Model were used and its results showed that the BSE Greenex index recorded positive return with the highest return. The ADF Test confirmed that the data attained the Unit root at level difference. The study also found that the BSE Greenex Index were volatile throughout the COVID 19 Pandemic Period. Thus the study concluded that COVID 19 Pandemic influenced the Indian Greenex sectors, during the study period.
