This study analyzed the correlation between Taiwan's business cycle and sand and gravel-related industry production value from January 1994 to December 2018, taking Taiwan sand and gravel–related industries (marble, limestone, serpentine, dolomite and other mining) as the research object. This paper takes the NATIONAL Development Council's business climate cycle benchmark date as the base period for analysis, get the following two main conclusions: First, all sand and gravel–related industries upstream and downstream production value, are lagging behind the peak of the business and the bottom of the valley, so the business rate for the paper–related industry are leading pointer, can be used as an important basis for pre–analysis. Second, during the peak period of prosperity, the gap in the degree of lagging behind of limestone is relatively small, and the gap in the bottom period is larger; in the recession period, the serpentine will fall more slowly, so limestone responds to the market downturn faster. In addition, this paper also uses the stock market benchmark date as the base period analysis, its research results and the above–mentioned roughly consistent, in the business and large market peak and valley average statistical analysis, the results of the study and the aforementioned conclusions are also exactly the same, showing the robustness of the results of this paper. |
