Two sessions: Suggestions and proposals for high-quality development

Wang Dujuan, chief engineer of China Railway Engineering Equipment Group and also an NPC deputy, suggested speeding up the electrification and greening of construction machinery.

The speed of electrification and greening of construction machinery is much lower than that of passenger vehicles, she said, suggesting the country should provide appropriate subsidies to new-energy construction machinery.

This will not only improve the global competitiveness of Chinese construction machinery, but also help prevent and control environmental pollution, she said.

"Over the years, we have continued to increase investment in sci-tech innovation, and we have experienced the benefits of high-quality development," she added.
