Huge investment has been undertaken but this is reflected only through a marginal shift in favour of the secondary

Correspondingly there has been a decline of almost an equal amount in the tertiary sector from 17.3 to 16.7 per cent.Colin dark has given a thesis about the pattern of occupational shifts with economic development: that as a country industrializes there will be a shift in the working force from primary to secondary and ultimately to the tertiary
