Evaluating the efficiency and productivity change within government subsidy recipients of a national technology innovation research and development program 下载免费PDF全文
Sungmin Park 《R&D Management》2015,45(5):549-568
This study analyzes the efficiency and productivity change within government subsidy recipients of a national technology innovation research and development (R&D) program. We examine 6,990 government‐sponsored, completed R&D projects during the last three performance follow‐up survey years from 2010 to 2012, and present a design of the sample of panel data to cope with the typical R&D performance time lag using a set of massive observations associated with completed R&D projects for the past 7 years from 2005 to 2011. In particular, data envelopment analysis is adopted to measure the efficiency and productivity change, which is measured in the Malmquist index. Parametric and nonparametric statistical tests are carried out to check for statistically significant differences among the characteristics regarding the types of government subsidy recipients. This study's major findings are as follows. First, during the entire period analyzed (2010–2012), there was a similar yearly pattern of statistically significant differences in the government subsidy means among the recipient types. In contrast, there were no obviously equivalent differences in the efficiency and productivity change. Second, the productivity had increased year on year, but the increments were reduced from year to year. Third, the productivity change was induced mainly by the Frontier‐shift, which indicates overall technology innovation progress, compared with the Catch‐up, which only indicates a simple increase in the efficiency. In particular, in this empirical analysis, the recipient types of ‘national laboratory’ and ‘large company’ had relatively larger sizes of government subsidies per project. However, the efficiency and productivity change of these types was not better than the others. This implies, therefore, that the government should control the ratio of the subsidy to the total R&D budget with an appropriate upper limit.
- I empirically evaluate the productivity change within a national technology innovation R&D program.
- I design a sample of panel data to cope with the typical R&D performance time lag using massive observations.
- There is no obvious relationship between the government subsidy size and R&D productivity change.
- Some particular types of government subsidy recipient are inferior in terms of R&D productivity change.
- It practically implies that the government should control the ratio of the subsidy to the total R&D budget.

人力资源需求预测方法探讨 总被引:3,自引:0,他引:3
由于经济全球化及信息技术的飞速发展,使得当今企业面临的内外部环境日趋复杂。如今,企业在进行人力资源需求的预测时,考虑的往往不是单个因素的影响,而是多种因素的共同作用和相互影响。因此,将人力资源需求预测方法总体上分为定性和定量两大类,对目前流行的各种需求预测方法进行分析比较,并根据其在实际中的应用提出了相应建议。 相似文献

河南艾滋病村驻村调查笔记 总被引:4,自引:0,他引:4
通过对艾滋病村和受艾滋病影响群体状况的直接观察和解释,揭示艾滋病疫情对当地社会经济发展、人民生活和社会稳定所造成的负面影响。政策建议:(1)为了避免更大的灾难,政府应当把遏止艾滋病作为“科学发展观”和“人口与发展战略”的一个组成部分,以便进一步动员各方面资源参与艾滋病的防治工作。(2)国家人口和计划生育系统应当全面介入国家的艾滋病预防。 相似文献

《Telecommunications Policy》2020,44(9):102011
This paper tracks increasingly aggressive initiatives by the United States government to reallocate spectrum on an expedited and unilateral basis well before conclusion of inter-governmental coordination. Rather than embrace the customary commitment to achieve consensus on global spectrum allocations at the International Telecommunication Union (“ITU”), the Federal Communications Commission (“FCC”) has auctioned off large blocks of frequencies for the next generation (“5G”) of wireless services.The FCC might have framed its first 5G auction, reassigning Ultra High Frequency (“UHF”) spectrum, as a one-time deviation from compliance with long standing, intergovernmental coordination procedures. These frequencies have ideal signal propagation characteristics and the Commission could use financial incentives—unavailable in most nations—to expedite “repacking” by incumbent broadcasters willing to move, share or abandon spectrum in exchange for ample financial compensation. However, the FCC has continued to auction off 5G spectrum on grounds that it must find ways to abate an acute shortage of wireless bandwidth and doing so will regain or maintain global leadership in wireless technologies. This paper offers a critical rebuke to unilateral spectrum management, because the short-term benefits expected by the U. S. government likely will be offset by countervailing harms to 5G manufacturers, carriers and consumers. The paper tracks fractious preparation for the ITU's 2019 World Radio Conference by the U.S. delegation and the mixed record achieved there. Additionally, the paper explains how injecting trade, industrial policy and national security issues at the ITU can trigger more delays and disputes, including possible retaliation by nations displeased with U.S. efforts to subvert traditional technology optimization goals.A worst case scenario has the ITU deadlocked and unable to reach closure on “mission critical” spectrum planning issues at World Radio Conferences, convened every four years. The paper concludes that costs and likely challenges to the efficacy and legitimacy of the ITU will reduce the benefits accruing from the FCC's unilateral, spectrum planning campaign. 相似文献
