dc.description.abstract |
The research attempts to evaluation impact of the Exports and Imports commodities in
the country economic. Mainly, following objectives are elaborated, behavior of the
exports and imports, to determine which type of commodity is mainly impact to the
country economic, to understand theoretically link between the total exports and
imports commodities groups and to revisit the total exports and imports groups by
investigating hidden factors which are impacting to county economic. The data are
collected mainly from 2007 to 2017 monthly basis from Central Bank of Sri Lanka
and Census & Statistic Department Sri Lanka. Although total Exports and Imports
commodities have been studied with many statistical and economical methods. The
researcher has tried to study the similarities of commodities groups and differences.
Various statistical techniques have been used such as Basic Statistical, Principle
Components (PCA), Factor Analysis (FA) and VARI-MAX Factor Rotation. With the
strong based on the preliminary analysis, there are strong correlations among the
commodities. This paper is adopted the Principle Component and Factor Analysis to
assess eights commodities groups by finding out the level of redundancy among them
from the correlations matrix and grouping indicators with higher similarities into the
same factors in Exports and Imports separately. According to the similarities,
Agriculture Exports, Mineral Exports and Consumer Imports and Investment Goods
Imports are categories accurately. But there is no proper grouping for Industrial
Exports & Intermediate Imports. Based on the rearrangement of commodities, seven
components are identified for Total Exports and eight components are identified for
Total Imports according to Factor analysis and improving the results using VARI-MAX
Rotations. Also, there are no rapid improvement for all commodities except Garments,
Tea and Petroleum sectors. These groups are highly impact to the Gross Domestic
Product (GDP) and it need reliable improvement to eliminate the negative impact for
country economic. Furthermore, Balance of the Trade is a negative value. When
determining which type of commodity is mainly impact to the country economic,
Garment & Textile, Tea & Petroleum Products are critical in Export sector. But, there
are lack of attention for agriculture sector. |
