According to the Reserve Bank of India, "In the era of globalisation and financial integration, foreign direct investment (FDI) has emerged as one of the most important forms of capital flows to developing countries. FDI is often preferred over other forms of capital flows by the policy makers as it is considered to be of a more stable nature." According to the data released by the Department for Promotion of Industry and Internal Trade, between 2010 to 2020, the average FDI rate brought in by West Bengal varied between 1 percent to 2 percent. RBI states that, "The prevalence of strong labour unions and large number of industrial disputes in the states of West Bengal and Kerala reflect the stringent labour laws and pro-labour government policies in those states. Such industrial disputes seriously hampers the profitability of the manufacturer and, therefore, has adverse impact on foreign investment."
