前瞻
前瞻的定義
前瞻目的在管理未來不確定性。系統性評估可能對競爭力、生活品質、財富創造等層面造成重大影響趨勢。前瞻本質乃以調查社會的意見來預測及勾勒未來情景需求。並藉調查過程形成共識目標,掌握長期科技發展脈絡,引導政策與策略的形成,建構完善的基礎建設與有利於創新的環境,使經濟與社會獲得最大效益。
前瞻活動納入政策決策機制是全球發展趨勢
前瞻議題教育的前瞻
教育政策及方法應探討如何培育創新理性思考之人才及建立終身學習的環境,並持續且有策略的爭取國際人才。教育前瞻已是刻不容緩的公共政策基礎。
科技的前瞻科技投資效益回饋的時程需十至二十年,且技術發展變化快速;如何掌握先機與發展方向是提升競爭力必要條件。
前瞻議題資源的前瞻
人口、能源、環境、水源、土地、海洋、物種等資源,需有長遠的策略規劃,以落實永續發展。
人文的前瞻社會的價值觀及生活方式,應從人文及環境的關懷出發,由產業、學界及社會共同塑造提倡,透過知識闡明及宣導,引導社會朝創新及永續發展,同時培養正確的生活態度及社會責任。
以推測並型塑長期社會 , 經濟 , 技術發展與需求為基礎,廣邀各界進行探索 , 討論與分析 ,形成願景與共識 .其過程實踐決策科學化與意見多元化,同時配合新的法規與教育政策 , 以因應未來的挑戰 , 是提升國家競爭力與永續發展所迫切需要之機制 .
五、結論與建議前瞻決策與永續發展

2009 STAG: General Observations
Since the 1980’s, Taiwan has successfully developed the semiconductor, information and communication technology (ICT) industry. However, to meet new challenges and improve the economy, Taiwan has recognized the need for diversification and development of new knowledge-based economy through investment in six emerging industries (SEI) to ensure the long-term sustainability and high quality of life.
Strategy • Some emerging industries, e.g. green energy
and biotechnology, require development of key technologies while others require adequate business models. The government should provide incentives and infrastructure to facilitate their development.
• Some emerging industries, e.g. green energy, are being aggressively pursued by other countries, Taiwan must make choices and focus on the areas which can become a world leader.
Academic Institutions in Taiwan
Innovations in research continue to accelerate in Taiwan and have built a strong foundation of knowledge for applications, but academic institutions need to have more flexibility to modify their programs to insure their graduates to have the knowledge and skills required for emerging industries and new challenges.
Discovery and InnovationBridging the Gap between Academia and Industry
discovery driven, not improvement based
DiscoveryInvention
Basic Research
Curiosity orProblem Driven
InnovationTranslational Research Products
Usable Technology
or Early Product Candidate
Value Creation from Innovation.Manufacturing and Marketing
Development of research projectA. Problem-driven 1. Identify an important scientific or technical problem
- design research – solution (tools, methods, composition).
2. Identify a significant disease problem – design research – solution (disease treatment, cure).3. ---- Other areas problemsB. Curiosity-driven Initiate a curiosity-based question - design research
– result (knowledge, tools)
Scientific Research and Accountability: Push and Pull
• Academic freedom vs social responsibility• Curiosity driven vs problem solving research• Intellectual property protection vs public
access to knowledge• Financial return vs social return• Policy making vs knowledge uncertainty• Participation and reward vs ethics and conflict

Trends in Healthcare and Biotechnology Industry
From disease treatment to personalized and preventive medicine.
Due to aging populations, the healthcare economy will reach US$ ~ 6 trillion in 5 years (~ 3 trillion will be from the biotech and pharmaceutical industry).
Asia will soon have 1/3 of the world market.
