nnnnn This study was first contemplated in late 1969, and active planning began in 1970. At that time, experience in regional input-output analysis in Australia was limited to a study of the Western Australian economy by Parker and a table of a town in New South Wales by McCalden. In this context the general objectives of this study were two-fold:nnnnnn (a) to investigate the problems involved in the construction of an input-output table of a large-area sub-state region in Australia, and to develop methods of table construction in the Australian regional context. This was intended as an exploration in regional economic analysis in Australia in a research area in which no previous experience was recorded.nnnnn (b) to undertake an analytical study of the Central Queensland region. This region had been the subject of concern to both university research workers and some government officials, due to a relatively slow growth rate, even decline in some sectors, and the unknown effects of the recent establishment of some large-scale industry. The input-output model was seen as providing the opportunity to quantify the Central Queensland economy, and to gain some appreciation of the regional impact of one large-scale industry (an alumina refinery) on the region.nnnnn A 26-sector input-output table of the Central Queensland region was compiled in purchaser's values for the 1965-6 year. This study details the compilation of the table with reference to data problems and collection, to valuation and aggregation, to the calculation of gross output, purchases and sales, and to the reconciliation of purchases and sales estimates. The problems raised by the data deficiencies led to the development of a general procedure for calculation of both row and column estimates of inter-sectoral transactions, and to the design of a procedure for their reconciliation to the required single-valued estimates. These sections relating to reconciliation procedure are seen as a contribution to input-output methodology on important matters conventionally omitted in published input-output studies.nnnnn Detailed discussion relating to the estimation procedures for each sector is provided. This discussion indicates the extent to which the statistics available from the Bureau of Census and Statistics needed to be supplemented by data from a variety of sources, including data collected by mail questionnaire, and provides some assessment of the value of the resulting estimates. The estimation measures employed vary widely, from the use of 'genuine' regional data to the modification of extra-regional and national coeffificents. The use of these estimation procedures may be evaluated in the light of the discussion in Chapter 2, relating to the development of regional input-output models.nnnnn A comprehensive input-output analysis follows the derivation and description of the Central Queensland tables. This analysis is presented in terms of structural and market analysis, and the calculation of output, income and employment multipliers. These procedures are further applied to the measurement of the impact of an alumina refinery on the regional economy.nnnnn Finally, some comment is offered on the value of the Central Queensland tables and multipliers, and some questions are raised relating to alternative analytical approaches, and to the resource requirements of this type of study.
