with relative efficiency (given its goals), in the sense that it secured products in demand and got them into the hands of consumers and producers, regularly, and with a minimum of delay. While profits of large importing houses tended to be repatriated, the sur- pluses of small firms remained in the country and found their way into either direct investments or the banking system, for the most part. The significance of these points is that the policy object of socialising internal trade has often been seen in Tanzania simply in terms of appropriating surpluses accruing to the commercial sec- tor; but since these profits were small and scattered (and in many cases depended upon the small size of operations) little positive national impact was possible with socialisation. That is not to say that other goals are not possible and worthwhile pursuing. The Second Five Year Plan articulates many such goals for internal and import trade. However, these aims were stated in terms of new areas of activity (more efficient location of processing, chan- nels for the expression of concumer tastes, clearing-house facilities, etc) but almost all changes in the internal trade field in fact have been directed at existing and it is precisely these where little needed to be done at this stage. This led, in turn, to a lack of a clearly stated objective function regarding the trade sector in general and S.T.C. in particular; among the consequences was a continual divergence of national and corporate goal. S.T.C. and the Tanzanian Economy S.T.C.’s impact upon the Tanzanian economy was extremely mixed, nearly polar. On the one side it was as if S.T.C. were a minor phenomenon. Because most of its 65,000 items were im- ported (its local produce was dominated by agricultural tools, fer- tilizers, cement, tyres, matches, sugar, steel, radios, batteries, soap and detergents, ghee, margarine, razor blades and iron roofing material it had a relatively small direct effect upon the vase majority of people in Tanzania, who consume almost exclusively local products. For the most part the large National Development Corporation subsidiaries had their own distribution networks (beer, shoes, cigarettes, for example). Imports for Government or parastatal project construction came through non-S.T.C. channels. The Corporation’s role as an exporter was minimal. The costs of S.T.C.’s capital programme were surprisingly low. 84
