    Abstract: 本文以 Romer(1990)的研發產品多樣化模型為基礎,考慮了營運資金與專利廣度,延伸建構一R&D 內生成長模型。在營運資金存在與不存在兩種情形下,透過模型分析政府補貼政策與專利政策對經濟成長率及社會福利的影響。
    本文發現,當政府提高補貼率與拓寬專利廣度,將使得經濟成長率提高,營運資金的存在則降低了政府政策對經濟成長的刺激。不論模型中是否存在營運資金,政府都有最適的補貼政策與專利政策能極大化社會福利。
    Based on Romer(1990), this thesis develops an R&D expanding variety model fea­turing working capital and patent breadth. The government instruments two policies: R&D subsidies and patent breadth. To shed light on the role of working capital, we deal with two situations. The first is the presence of working capital. The second is the ab­sence of working capital. We then use the model to examine how government policies affect the economic growth rate and social welfare under these two distinct situations.
    Two main findings emerge from the analysis. First, following an increase in the R&D subsidy rate and patent breadth, the economic growth rate will rise in response. Meanwhile, the presence of working capital tends to mitigate the growth effect of these two policies. Second, regardless of whether working capital is present or absent, the government can choose the optimal values of the R&D subsidy rate and patent breadth that maximize social welfare level.
