Productivity is the relationship between output and inputs used in the process. Cost based productivity is the ratio between output cost and inputs cost. Material Cost, overhead cost and conversion cost productivities are measured and analyzed with the total cost of sugar production. This article focuses on cost based productivities of 13 select co-operative sugar mills in Tamil Nadu for 13 years from 2006 to 2018. Goal is to reduce the total cost by improving the productivities. 13 select co-operative sugar mills have been collectively taken together for analysis. Every firm has to improve its productivity for its survival and prosperity. Result of the AUTO REGRESSIVE DISTRIBUTED LAG (ARDL) model shows that there is long run and short run relationship between the Material Cost productivity, Overhead cost productivity, conversion cost productivity and Total cost. The null hypothesis there is no co-integration between total cost and elements of productivities has been rejected. The study also proves that there is short run relationship between the variables through Co-efficient diagnostic Wald test. It also indicates that material cost, overhead cost productivity and conversion cost productivities are jointly affecting the total cost. It evidences that the total cost of sugar production is significantly associated with cane cost of productivity and overhead cost productivity and conversion cost productivity.
