台灣的經濟在1951年前是以輕工業和農業為基礎，直到1951年至1988年間是以勞動密集型工業為主，以關稅提高、進口限制、外匯管制等方式，使台灣經濟活動從由輕工業和農業社會轉為工業社會。 　　
1970年代石油危機爆發，全世界的經濟受創台灣也不例外，當時蔣經國總統發起十大建設，讓往後的重工業以及石化工業奠定了良好的基礎，隨著十大建設的引響，砂石業也跟著蓬勃發展，砂石的採集分類篩分….等。
2008年至2015年間勞動密集型工業逐漸地被電子產業代替。隨著台灣經濟基礎的更變轉型，不管是化工業，食品業，砂石業……等，對物質篩分分級的需求是沒有更變的，隨著科技的進步篩網擁有個更多材質的選擇， 本研究將探討篩網的風險管控，本研究結果可以提供使用篩網的各個行業作為篩網使用相關的參考依據。

Taiwa ’s economy was based on light industry and agriculture before 1951. From 1951 to 1988, it was mainly labor-intensive industry. By increasing tariffs, import restrictions, and foreign exchange control, Taiwan ’s economic activities were shifted from light industry and agriculture. The agricultural society turned into an industrial society. 　　
The oil crisis broke out in the 1970s and the world economy was damaged. Taiwan is no exception. At that time, the National President Chiang Ching-kuo launched ten major projects, laying a good foundation for the future heavy industry and petrochemical industry. The industry is also booming, collecting, sorting and screening sand and gravel. 　　
From 2008 to 2015, labor-intensive industries were gradually replaced by the electronics industry. With the transformation and transformation of Taiwan's economic foundation, whether it is the chemical industry, food industry, sand and gravel industry, etc., the demand for material screening has not changed, and through the advancement of technology, the screen has a more material s Choice, This study will discuss the risk management of screens. The results of this study can provide a reference for the risks associated with screens in various industries that use screens.
