Does Military Spending Nonlinearly Affect Economic Growth in South Africa?

Using annual data collected from 1988 to 2015, this study provides evidence of a non-linear relationship between military spending, economic growth and other growth determinants for the South African economy. The empirical study is based on estimates of a logistic smooth transition regression (LSTR) model and our empirical results point to an inverted U-shaped relationship between military spending and economic growth for the data. Furthermore, our empirical results suggest that the current levels of military spending, as a component of total government expenditure, are too high in the South African economy and need to be transferred towards more productive non-military expenditure in order to improve the performance of economic growth and other growth determinants.     

舰艇作战系统工作模式及其作战对策分析*

探讨了基于敌情事件触发的舰艇作战系统工作模式及其作战对策。根据舰艇的内外部需求,依据传感器系统与武器系统所处的状态,提出了舰艇作战系统的五种工作模式。并研究了在敌情事件触发下,如何根据舰艇所处的工作模式,迅速做出相应的作战对策,给出各种模式下的模式转换流程。这种作战对策可使作战过程自动化、信息传输扁平化,从而提高舰艇在紧急状况下的反应速度。
