Change in economy is not a random incidence. It is a long term process which implies change in mode of production. Among five sectors of economy three sectors namely primary, secondary and tertiary are most important for any developing country. West Bengal being a State of a developing country has its economic root in agriculture. But it has been observed that with the march of time the contribution of primary sector to Gross State Domestic Product (GSDP) is declining and that of secondary sector especially the contribution of manufacturing units is also going down. The economy of Haora district is based on secondary activities mainly manufacturing and processing since the colonial period. But day by day the share of registered manufacturing units in Net District Domestic Product (NDDP) is deteriorating while the share of unregistered manufacturing units is rising which indicates an insecure mentality of the entrepreneurs. In fact an inter-sectoral shift has been observed in the district as revealed from the deteriorating contribution of the primary and secondary sectors to NDDP whereas the tertiary sector is flourishing. Such an economic condition indicates a low productive economy with wide scale unemployment. In fact slow growth of the different categories of industries and their sickness in all scales of operation has altered the economic composition of this industrially advanced district. The tertiary sector alone cannot make a strong economy. Thus without revival of the manufacturing units, rejuvenation of the economic structure is impossible and balanced economic growth cannot be achieved.
