Based on China's strategic transformation from a manufacturing country into a creative country, this paper outlines the characteristics, trends, and value of Design 3.0 in the era of the knowledge network, and discusses the factors and implications of competitiveness in innovative design. On the basis of the three indices of benefit, design capability, and design environment, these authors construct a three-in-one evaluation system for design competitiveness that comprises national, urban, and enterprise-based competitiveness in innovative design. This study divides various countries, cities, and enterprises into data samples, and carries out a pilot evaluation. The authors then summarize policy recommendations and specific measures to enhance China’s innovative design competitiveness.
