The key purpose of the study is to investigate the relationship between Greenfield investment and economic growth of Bangladesh using annual time series data during the period 2003-2020. The study employs Toda-Yamamoto (T-Y) tests of Granger causality method that performs Modified Wald Test (MWALD) in order to establish causal relation among different variables. There are three steps in implementing the T-Y procedure. The first step involves using different tests (ADF, PP, and KPSS test) to identify the maximum order of integration of the variable. The second step requires selecting the optimal lag length () based on several lag length selection criteria. In the third step, MWALD approach is used for testing the vector auto regression model for causality. The results of the tests (ADF, PP, and KPSS) concluded that the maximum order of integration of the variables is two. Then, the optimal lag length of two ( = 2) has been selected based on several lag length selection criteria. Finally, the findings reveal the evidence of unidirectional causality from Real Greenfield Foreign Direct Investment (RGFDI) to Real Gross Domestic Product (RGDP). The key contribution of this study is to investigate the Greenfield investments-growth relationship for a country like Bangladesh.
本研究的关键目的是利用2003 - 2020年期间的年度时间序列数据,调查孟加拉国绿地投资与经济增长之间的关系。该研究采用格兰杰因果关系方法的托达 - 山本(T - Y)检验,即进行修正沃尔德检验(MWALD),以建立不同变量之间的因果关系。实施T - Y程序有三个步骤。第一步涉及使用不同的检验(ADF、PP和KPSS检验)来确定变量的最大积分阶数。第二步需要根据几个滞后长度选择标准选择最优滞后长度( )。第三步,使用MWALD方法检验向量自回归模型的因果关系。检验结果(ADF、PP和KPSS)得出变量的最大积分阶数为二。然后,根据几个滞后长度选择标准选择了最优滞后长度二( = 2)。最后,研究结果揭示了从实际绿地外国直接投资(RGFDI)到实际国内生产总值(RGDP)存在单向因果关系的证据。本研究的关键贡献在于调查了像孟加拉国这样一个国家的绿地投资与增长之间的关系。
