This paper attempts to build a simple indicator of state power. Military expenditure is the paper’s point of departure, with the definitions given by NATO, SIPRI and others. This definition is discussed and a power version is build, using French budgetary data. Then a defence of the result against traditional or non-traditional critics is presented under an imperative of action. Finally, this concept is enlarged and a new concept of power expenditures is given, one more time using French budgetary data. The conclusion is that this large expenditure concept is an unbiased but imperfect indicator of the will to act, and has to be completed by GDP to indicate the capability to act in the long-run. 相似文献

ABSTRACTThe European arms industry is challenged by several adverse “headwinds.” Fragmentation leads to costly duplications and, in conjunction with stagnating budgets and sharply increasing costs, prevents firms from exploiting economies of scale and learning. This is exacerbated by size differentials vis-a-vis the leading US arms manufacturers and competition from emerging producers. As some “headwinds” are self-enforcing, far-reaching industrial and policy responses are required to improve the industry's outlook. As exports may not indefinitely compensate for low domestic demand, there is an economic imperative for further cross-border collaboration and consolidation. Despite various EU policy initiatives, progresses regarding the European Defence Equipment Market and strengthening the European Defence Technological Industrial Base have been relatively slow. It remains to be seen whether the European Defence Fund will be the proclaimed “game-changer,” raising competitiveness of the European arms industry. At the same time, the UK's withdrawal from the EU adds uncertainties. 相似文献

This article analyses the economic impact of the expenditure budget of the Spanish Ministry of Defence (MoD) and its Autonomous Agencies (AA), distinguishing direct, indirect and induced effects. The input–output methodology is used to find intersectoral effects on the rest of the economy. The article quantifies the economic impact in terms of production, gross value added (GVA), employed population, tax revenue, and also in terms of its contribution to the gross domestic product (GDP) of Spain in 2010. The results show that the activity of the MoD and AA generates 1.2% of the country’s GDP and 1.7% of total employment in that year. 相似文献

ABSTRACTWith the world’s ninth largest economy and comprising nearly 60% of South America’s GDP, 47% of its territory, and 49% of its population, Brazil has become a regional power and an important actor in world affairs over recent decades. This scenario has led the government to re-evaluate its role in the world order, resulting in the enactment of the National Defence Policy, whose objective was to consolidate the country as a regional power while at the same time addressing national security issues, promoting economic development through a series of defence programmes, restructuring the defence industrial base, fostering innovation through technology and knowledge transfer to Brazil, and indigenous research and development. However, the policy’s implementation suffers from several challenges discussed in this article, which may test the capability and competence of Brazilian policymakers, military, industrialists, and other individuals and organisations involved in its implementation. 相似文献

Russia has long been pursuing an intended and calculated policy of keeping enough influence in Bulgaria in order to have control over national decisions. Together with the economic, energy, political and information tools used by Russia in its hybrid war against Bulgaria and in its bid to achieve an enduring “state capture,” defence is also a distinct target of Russian subversion now. A list of noticeable subversive actions with tangible effects can be summarised, ranging from fuelling division and manipulating public opinion, preventing the strengthening of the NATO position in the Black Sea, sabotaging defence reform to various options of subverting the modernisation of the Bulgarian Armed Forces and seeking new ways to keep legacy Soviet military equipment in operation as long as possible. This issue must be urgently addressed both nationally and in NATO. 相似文献

ABSTRACTIn analysing trends in Chinese defence engagement and their impact on defence development in African states, it is important to consider both China's changing policy priorities and its capabilities for the provision of defence support. China's international ambitions and its economic development contribute to its emergence as a key supporter of defence capability development in Africa, occupying a crucial niche as a provider of support, particularly arms transfers, appropriate to evolving local requirements. The economic and politico-military imperatives driving China's engagement of Africa, which stem from its economic reforms and re-emergence as a great power, are facilitating defence modernisation by accelerating the introduction of modern arms in substantial quantities. The commercial importance of arms exports and the growing importance of strategic ties strongly situate China to help sustain processes of defence capability development in African states over the long term. 相似文献
