| Summary: | 碩士 === 淡江大學 === 產業經濟學系 === 85 === Research and Development (R&D) is the main resource
for technologyadvancement.Due to the spillover effect form
firm''s R&D,R&D resources tend tobranch out.Government policy
now can motivate firm''s R&D indination throughdifferent
industrial policies,so that individual firm R&D benefits our
societythe most.Therefore,researches about R&D spillover
effects and governmentindustrial policies are the major course
of industrial organization theorem. First of all,this
article presents a simple Cournot duopoly model todiscuss
the best suitable policy government should take under different
firm''scompetitiveness.Research of this artical shows the
following conclusion:(1)When firm''s competitiveness becomes
individual R&D and output competition,government will subsidize
the firm''s output.However,R&D spillover effects willaffect the
government''s direction of R&D policy. (2)When firm''
scompetitiveness becomes cooperative R&D and output competition,
government willsubsidize both firm''s R&D and their
output phase.(3)When firm''scompetitiveness becomes
cooperative R&D and output collaboration,governmentwill still
subsidize cooperative firm''s output,but will not interfere
withcooperative firm''s R&D.
Secondly, this article also discusses our government''s most
suitableindustrial policy and trading policy when our firm
proceed with tradingcompetition in the third country and
compare our analysis with Spencer &Brander (1983)
conclusion.The result are: (1)When our government policy
isonly towards our firm''s R&D,our government will subsidize
R&D unless R&Dspillover is 0.5. (2)When both governments
take R&D policy towards the 2ndcountry''s firms, the
governments both provide R&D subsidiary.If
bothgovernments'' goal is maximum joint social welfare,R&D
spillover will affectthe two government''s direction of most
suitable R&D policy.(3)When ourgovernment also considers
taking exporting policy toward our firm,thisresearch points
out that when R&D spillover is lesser,our government collectsR&
D taxes from our firm, but provide exporting subsidiary
for theiroutput.However,when R&D spillover is greater,our
government policy will beaffected by the firm''s R&D unit cost.
