This study investigates the relationship between Foreign Direct Investment (FDI) inflows and economic growth at sectoral levels in Bangladesh, employing a panel study framework. Utilizing sectoral-level panel data spanning six sectors from 2007–08 to 2018–19, the analysis is conducted using Panel Vector Error Correction Model (Panel VECM). Results from panel unit root tests confirm that all variables are integrated of order one I (1), indicating stationarity. The Pedroni panel co-integration test further supports the presence of co-integration among the variables. Notably, the Panel VECM reveals evidence of a unidirectional causal relationship from Real Gross Domestic Product (RGDP) to Real Foreign Direct Investment (RFDI) across all six sectors of Bangladesh. The findings underscore the significance of formulating pragmatic policies and implementing them effectively to attract FDI across sectors, thereby contributing to the overall economic growth of Bangladesh.

本研究采用面板研究框架，探讨孟加拉国分行业维度下外商直接投资（Foreign Direct Investment, FDI）流入与经济增长之间的关联关系。本研究使用覆盖2007-08至2018-19年共6个行业的分行业面板数据，采用面板向量误差修正模型（Panel Vector Error Correction Model, Panel VECM）开展实证分析。面板单位根检验（Panel Unit Root Tests）结果证实，所有变量均为一阶单整I(1)，具备平稳性。佩德罗尼面板协整检验（Pedroni Panel Co-integration Test）进一步验证了变量间存在协整关系。值得注意的是，面板向量误差修正模型结果显示，孟加拉国全部6个行业均存在从实际国内生产总值（Real Gross Domestic Product, RGDP）到实际外商直接投资（Real Foreign Direct Investment, RFDI）的单向因果关系。本研究结果凸显了制定务实政策并有效落实以吸引各行业外商直接投资，进而推动孟加拉国整体经济增长的重要意义。
