The feasibility test by inter-industry analysis has been attempted to examine any im- balances ir the economy. From the Leontief inverted transaction matrix of the inter-in- dustry table for the economy of British Guiana 1959 (Tables 6c and 6d), total supply of goods and services necessary to meet the projected final demands (i. e. government and household expenditures, exports and gross domestic capital formation) have been esti- mated for 1965-75. Allowing for imports in the same proportions of imports to total supply as in 1959, we have obtained the "needed" domestic outputs. The ratios of these "needed" domestic outputs to our sectoral growth domestic outputs (Table 2. 5. ix) show that a larger proportion of imports than in 1959 will be necessary to balance the economy. However, by 1975 livestock, forestry and fishing, chemicals, other manufacturing, and fuel and power will be well advanced in their bid towards import substitution, and engi- neering will also make significant progress. An interesting fact is that mining has more export potential than at present and even by 1975 it will not be fully exploited. The major bottlenecks appear to be the agriculture and food processing sectors, where imports will be increasing, and also the building and construction sector which would require more expansion. On the other hand, distribution, transport and communications, banking and insurance, and professions and personal services will be more than adequate. Thus the imbalances in the economy require significant efforts in import substitution activities, especially in processing and manufacturing industries.
