TOTAL FACTOR PRODUCTIVITY TRENDS: AN ANALYSIS OF TRANSPORT EQUIPMENT AND PARTS INDUSTRY

The present study is confined to manufacture of transport equipments and parts industry of organised
manufacturing sectors of Punjab for the period of 1980-81 to 2002-03, at three digit level. Major source of
data for the study is Annual Survey of Industries (ASI). Growth rate of total factor productivity is positive and
significant for the transport equipment and parts industry in pre-reform period ; however, this momentum
could not be maintained in post-reform period, where growth rate turned to negative. Growth rate of total
factor productivity of transport equipment and parts industry and at its disaggregate level [manufacture of
motor vehicle industry (NIC-341), manufacture of railways and tramway locomotives and rolling stock industry
(NIC-352) and manufacture of transport n.e.c. industry (NIC-359)] is higher in pre-reform period as
compared to the post-reform period.
