  本研究主要探討水泥工業在整體產業發展中所扮演的角色以及其未來可能的發展方向。
  本研究結合投入產出法、因素分解法及不確定決策理論等三種方法,對水泥產業能源使用以及環境品質之相關性作探討,研究結果的重點摘要如下:
  1.就水泥業歷年之感應度而言,皆低於產業平均水準且其在全體產業中之排次並不高,顯示水泥業所能誘發之向前開聯效果不顯著。另外,就其影響度及其在全體產業中之排次來看,影響度略高於產業平均水準,然其影響度排名列於第九至十七名間,顯示其貢獻並非十分顯著。
  2.水泥業之總能源乘數,自民國70至80年間減少26.4%,顯示水泥業體能源使用效益有改善的趨勢,而整體產業的能源乘數排序中,數年來皆名列前四位,顯示水泥業為高耗能產業。
  3.水泥業之污染乘數,歷年來除SO2污染乘數居前六位外,Co2、NOx及TSP污染乘數在整體產業之排次均高居第一、二位,屬於高污染產業。
  4.若適度地以水泥進口替代國產水泥,不僅能防止國內水泥業者之寡佔壟斷,另外列能減少能源耗用與降低環境污染,據本研究估計:平均每進口一公噸水泥可減少能源耗用9.54×105Kcals以及降低CO2排放量0.75公噸。雖水泥進口有進口來源之不確定風險,但仍不失為值得考慮之政策。


  This study uses input-output analysis, factor analysis and uncrratinty decision making theory to analyze the interrelationship between energy use and environmental quality of Taiwan's cement industry. The main focus is on CO2, SO2 and NOx emissions from energy inputs of the cement industry in Taiwan. Major findings of this study are summarized in the following:
  1. The sensibilities of dispersion of the cement industry for years 1981, 1984,1986 and 1991 in this study are all less than one, and overall (compared to all industries ) are even lower; while the powers of dispersion for these years are greater than one. This means that the cement industry has more dispersion power in promoting and absorbing other industry's products and has less forward linkage effect in supporting other industries as input.
  2. The total energy multiplier of the cement industry has reduced 26.4% from 1981 to 1991; therefore the efficiency of energy use for producing ecment in Taiwan for these years has been improved. But the energy multipliers of the cement induystry in the whole industries for these years are all in the top 4. This means that the cement industry is among one of the high energy demand and high pollution industries. The increase of total impact of energy multipliers are alrgely due to indirect effects rather than direct effects.
  3. The pollution multipliers of the cement industry for thess years, except for the SO2 multipliers are in the top six, while the CO2, Nox and TSp multipliers are ranked either first or second overall, indicating again that the cement industry is a high pollution industry.
  4. Results of this study suggest that if the importable cement substitute mildly for the domestic cement, th ecement consumers can be protected from a few monopolies, in addition, the energy consumption and pollution emissions will be reduced. On the whole, an average of 9.5×105 Kcals energy and 750 Kg of CO2 emission can be reduced by importing 1000 Kg cement. Consequently, importing cement from other countries has the imherent uncertainty risk of source supply, but it still is a reasonable alternative for decision makers to consider.
