Ongoing globalization and changing customer needs make it increasingly difficult for firms to survive in the long term. Innovation is considered an important tool for firms in this environment. In particular, a firm’s ability to cultivate innovative behaviour and implement product innovation for sustainability is important. This study explores resources and capabilities to enhance firm innovation behaviour and implementation of sustainable product innovation. The results provide insights on how firms can manage strategies for future sustainable innovations. We used a sample of 645 small- and medium-sized enterprises and presented the conceptual framework according to a resource-based view and relational capital. We specified three independent factors that enhance sustainable innovation and superior performance: market orientation, managerial ties, and government support. We used a questionnaire survey and structural equation modelling to evaluate the conceptual model. We found that interactions between business ties, customers, and competitor orientation can enhance sustainable product innovation, whereas interactions between government support and political relations can enhance the sustainability of innovation behaviour. Moreover, product innovation and innovation behaviour are mediators that can lead to superior firm performance. The results suggest ways entrepreneurs and public policy makers can promote sustainable innovation.

Using the daily, weekly and monthly data of Morgan Stanley Taiwan Index' Component Stocks from January 1998 to June 2004 as example, this paper try to improve the investment performance of technical analysis indices. First of all, this paper whitens original data through a grey model GM (1,1), and grey technical analysis indices are obtained. We use traditional technical analysis indices like RSI, BIAS, KD as agency indices, compare the investment performance between original and grey technical analysis indices. Based on the empirical result using frequency statistics and Sharpe and Treynor index, we find:1.The investment performance using the original technical indices is better than that of the Taiwan stocks market weighed average index. 2.The portfolio investment performance using grey technical analysis strategy is better than that of buy-and-hold strategy and using traditional technical analysis strategy by Sharpe and Treynor index separately.3.The investment performance of technical indices can be increased more effectively through a grey forecasting model GM (1,1).The investment performance of original technical analysis indices strategy increases significantly after using the grey technical analysis indices. The annually performance as geometric mean increases 278.5%. The weak-form market hypothesis in Taiwan stocks market could be rejected under some fact.

This paper uses a grey forecasting model GM(1,1) on improving the investment performance of classical Markowitz efficiency frontier's investment portfolio using the component markets' indexes of MSCI World Index from 1999 to 2005 as the samples. Using grey Markowitz efficiency frontier's investment portfolio models, we establish a more stable and correct connection between ex-ante model and ex-post performance. The results show the Grey Markowitz efficiency frontier investment portfolio model could improve the investment performance effectively and stably.
